How to Beat an Obviousness Rejection at the Patent Trial and Appeal Board
Do you want to know how to beat an Examiner's 35 U.S.C. §103 obviousness rejection at the the Patent Trial and Appeal Board (PTAB)? Then it helps to read decisions where the PTAB reversed an Examiner's obviousness rejection. Today the PTAB did exactly that in the Ostrovsky decision, which involved catheters.
In today's Ex Parte Issac Ostrovsky (Appeal No. 2011-009091) decision, the claims involved an imaging catheter having distal and proximal ends and a lumen. The Examiner's argument went as follows: The Examiner asserted that the Ben Hain reference "discloses an imaging catheter for use in intracardiac drug delivery including an imaging element at the distal end." The Examiner also noted that Ben-Haim "fails to disclose the use of a coaxial cable for running the system in parallel with the sensor." Furthermore, the Examiner found that Sieben "teaches the use of a coaxial cabling, wherein the sensor and the imaging transducer are electrically coupled in a parallel configuration." The Examiner went on to conclude that "[i]t would have been obvious to one of ordinary skill in the art at the time of the invention to have included the connection components of Sieben with the system of Ben-Haim et al for the purpose of providing the best signal and clearest diagnostic image possible with very little loss or distortion from noise or crosstalk."
The Appellant argued that "Sieben does not teach or suggest a sensor adapted to communicate with a medical positioning system and an imaging transducer in a parallel electrical configuration with respect to the sensor as recited in claim 1." The Appellants also asserted that the "CCD arrays of Siben are not 'adapted to communicate with a medical positioning system' as recited in claim 1," but are "used to receive the signals from the ultrasound transducer. Appellants thus asserted that the "CCD arrays do not correspond to the claimed sensor and any teaching regarding them is irrelevant to the invention of claim 1."
The Board agreed with the Appellants that the Examiner had failed to set forth a prima facie case of obviousness. Specifically, the Board held:
"Rejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness." In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006), cited with approval in KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 417-18 (2007). Here, the Examiner points to two disparate teachings in the Sieben reference, but does not explain how the coaxial cable relates to the CCD array relates to the coaxial cabling, or how the teaching of the CCD array by Sieben relates to "a sensor adapted to communicate with a medical positioning system, wherein the sensor and the imaging transducer are each electrically coupled, in a parallel electrical configuration with respect to each other, to the center wire and the outer shield at the distal end of the coaxial cable," as required by claim 1. The rejection is thus too cursory to pass the Kahn test, and it is thus reversed. (Emphasis added
Lessons Learned: Read an Examiner's 35 U.S.C. §103 obviousness rejection carefully to make sure he or she has met the Kahn test. Has the Examiner explained how one references related to the other reference? Has the Examiner provided some rationale or logic as to how the references would be combined? Has the Examiner simply stated a conclusion that it would be obvious to combine references? These are the questions you should be asking yourself when determining whether to attach a 103 obviousness rejection for failing to meet the Kahn test. If you feel the Examiner has not met this test, then you may have grounds for a reversal at the PTAB.

The Board Chimes in on Broadest Reasonable Interpretation and Obviousness Arguments
In one of its first decisions today, the Patent Trial and Appeal Board (PTAB) upheld an Examiner's 35 U.S.C. 103 obviousness rejection, citing, as it often does, the KSR v. Teleflex case. This blog post outlines the broadest reasonable interpretation standard and how it relates to 35 U.S.C. 103 obviousness rejections.
In today's Ex parte White (Appeal No. 201100327) decision, the claims involved an ultrasonic consolidation process across the surface of a multi-layered object. At issue was the plain meaning of the disputed term "optimizing" in a claim and whether it encompasses making a process as effective or functional as possible. The Board contemplated whether the Examiner's finding that the prior art's process optimizes the lateral positioning of its sonotrode relative to the geometry of the object being worked upon was reasonable, and the Board further contemplated whether it was reasonable that the process of the prior art would have been as effective or functional as possible.
Appellant provided no evidence or any persuasive line of reasoning explaining why the Examiner's finding of reasonableness was in error.
The Board first explained the broadest reasonable interpretation standard:
It is well established that "the PTO must give claims their broadest reasonable construction consistent with the specification ... Therefore, we look to the specification to see if it provides a definition for claim terms, but otherwise apply a broad interpretation."In re ICON Health & Fitness, Inc., 496 F.3d 1374, 1379 (Fed. Cir. 2007) ("[A]s applicants may amend claims to narrow their scope, a broad construction during prosecution creates no unfairness to the applicant or patentee."). The Board further stated that:
The Examiner's determinations that one of ordinary skill would predictably optimize the location or position of an ultrasonic welder (Ans.7), and predictably desire to minimize bulk motion (id. at 9), are supported by a preponderance of the evidence and are unrefuted on this record. An improvement in the art is obvious if "it is likely the product not of innovation but of ordinary skill and common sense."KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398,421 (2007). See also, Perfect Web Techs., Inc. v. InfoUSA, Inc., 587 F.3d 1324, 1329 (Fed. Cir. 2009) ("hold[ing] that while an analysis of obviousness always depends on evidence that supports the required Graham factual findings, it also may include recourse to logic, judgment, and common sense available to the person of ordinary skill that do not necessarily require explication in any reference or expert opinion").
And thus, since it was reasonable for one of ordinary skill to optimize the location or position of an ultrasonic welder, the Appellant's claims were obvious.
Lessons Learned: When attacking a claim construction in response to an Examiner's 35 U.S.C. §103 obviousness rejection, the savvy patent practitioner should cite evidence. In this case, the practitioner used attorney argument, which is cheap, to combat what he thought was an unreasonable interpretation of the claims. What he should have done was cite some solid evidence (textbooks, treatises, etc.) that supported his argument that one of ordinary skill would NOT have optimized the location or position of an ultrasonic welder. This would have created a higher bar for the Examiner to pass and may have resulted in a reversal at the PTAB.

Attacking References Individually: Obviousness Rejection Upheld by the Patent Trial and Appeal Board
Today, the Patent Trial and Appeal Board (PTAB) upheld an Examiner's 35 U.S.C. §103 obviousness rejection in light of the KSR v. Teleflex case. This blog post highlights those fundamental elements of an obviousness rejection that the PTAB seeks when upholding an Examiner's decision.
In today's Ex parte Naoki Soejima (Appeal No. 2011-000339) decision, the claims involved a method of manufacturing a cover for a vehicle airbag. At issue was a claim element reciting a teaching line corresponding to a linear groove, wherein the teaching line is formed in an airbag cover supporting surface of an airbag cover supporting jig.
Appellant argued that the prior art did not teach or suggest the claimed invention, in part because the prior art did not disclose that its teaching line is formed in the surface of a supporting jig.
The Board held the Appellant's argument was "unavailing since they fail to consider the prior art as a whole." The Board cited In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) ("Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of references."). The Board further stated:
"For obviousness under § 103, all that is required is a reasonable expectation of success." In re O'Farrell, 853 F.2d 894, 904 (Fed. Cir. 1988). Appellants have not specifically disputed the Examiner's determination that Bauer discloses teaching data by tracing a groove formed in a workpiece (Ans. 7-8; Reply Br. 2); or that Honma discloses "it is known to teach profiling data by tracing the workpiece support (i.e., jig) (column 2, lines 6-55)" as opposed to the workpiece itself (Ans. 4, App. Br. generally; Reply Br. 3). See also Honma, col. 1, ll. 45-57 (describing known use of an auto-teaching method in which a teaching operation is performed using a jig). In this regard, a preponderance of the evidence supports the Examiner's determination that the claimed invention merely applies a known alternative technique of using a supporting jig versus the workpiece for obtaining profiling data to yield predictable results (Ans. 5, 7). See KSR, 550 U.S. at 416 ("The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results."). Appellant has not adduced any persuasive technical reasoning or otherwise in response to the Examiner's reasonable determination ..." (Emphasis added)
Lessons Learned: When responding to an Examiner's 35 U.S.C. §103 obviousness rejection, it is not enough to argue that the cited references, individually, do not disclose your claim elements. This is a common tactic among patent practitioners and I, myself, am guilty of this. As explained above, In re Merck stands for the notion that "non-obviousness cannot be established by attacking references individually." Therefore, the best approach would be to both attack the cited references individually and attack the cited references in combination. In the case above, the Appellant would have been smart to include an explanation of why the two references combined would not have yielded the claimed invention. This would have satisfied the PTAB in providing an argument that responded to the Examiner's assertion that the combination of references rendered the claims obvious.

How to use the "teaches away" argument against a 103 obviousness rejection
In an interesting decision yesterday, the Board of Patent Appeals and Interferences (BPAI) affirmed an Examiner's obviousness rejection of a software invention, partly based on the Appellant's improper use of the common "teaches away" argument. This post highlights hot to use use the "teaches away" argument when responding to an Examiner's 103 obviousness rejection, especially when procuring software patents.
The case of Ex parte Ruiz (Appeal No. 2012-00970) involved a GoDaddy software invention used to register domain names. In responding to a 103 obviousness rejection, the Appellant argued that the cited references - Fellman and Gardos - could not be combined because one of the references taught away from doing so. In short, the Appellant provided a standard "teaches away" argument.
The Board started by citing law: "A reference may be said to teach away when a person of ordinary skill, upon [examining] the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant." Para-Ordnance Mfg., Inc. v. SGS Importers Int'l, Inc. 73 F.3d 1085, 1090 (Fed. Cir. 1995) (quoting In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994)). Then, the Board responded to the Appellant's arguments: Appellants argue Gardos "teaches away from the concept of querying an internal database" (App. Br. 21). However, as set forth above and as indicated by the Examiner, Gardos discloses querying an internal database. Gardos cannot "teach away" from a disclosure that Gardos provides. Further, even assuming (without deciding) that Appellants' characterization of Fellman and Gardos is correct, Appellants' have not indicated how either Fellman or Gardos discourages one of ordinary skill in the art from "following the path" set out in either reference or would lead one of ordinary skill in the art in a "divergent" direction (i.e., querying a database). We therefore are not persuaded by Appellants' argument.
So apparently, the Gardos reference disclosed the very act - querying an internal database - from which the Appellant argued that Gardos was teaching away. Further, the Appellant could not adequately point out how Gardos taught away.
Lesson Learned? This decision teaches us two things about effectively using the "teaches away" argument. First, if you are going to argue that a reference teaches away from doing X, then you should make sure the reference itself doesn't mention X. If it does, the "teaches away" argument would not be appropriate in that case. Secondly, if you are going to argue that a reference teaches away from doing X, then you should be able to point to some convincing language in the reference that explicitly states the reference should not or cannot do X. If you cannot find such language in the reference, then again, the "teaches away" argument would not be appropriate in that case.

Today, the Board of Patent Appeals and Interferences (BPAI) reversed an Examiner's rejection based on the "well-known prior art" argument. This Quick Post highlights the obligations that must be met by an Examiner when utilizing this form of rejection.
Recall that M.P.E.P. §2144.03 states:"Official notice without documentary evidence to support an examiner's conclusion is permissible only in some circumstances. While 'official notice' may be relied on, these circumstances should be rare when an application is under final rejection or action under 37 CFR 1.113. Official notice unsupported by documentary evidence should only be taken by the examiner where the facts asserted to be well-known, or to be common knowledge in the art are capable of instant and unquestionable demonstration as being well-known." Thus, "official notice" should only be used in certain, well-defined circumstances. Note the requirement that the "well known prior art" must be capable of instant and unquestionable demonstration as being well-known. As a comparison, see my blog post from last year regarding the obligations that must be met by an Examiner when using an inherency rejection.
In today's Ex parte Chapman (Appeal No. 2009-010238) decision, the claims involved a web browser related invention. With regard to one claim element pertaining to information that is communicated via telephone or email, the Examiner's 35 U.S.C. §103 obviousness rejection included the statement: "it is well known in the art that a customer contacts a customer service representative via telephone or email." That's all the Examiner had to say about that claim element. He did not cite to a patent, an article or any other tangible prior art reference. He simply stated it was well known prior art.
The Board did not agree with the Examiner's use of the "well known prior art" rejection. The Board decided: "we find that simply asserting that 'it is well known in the art that a customer contacts a customer representative by phone or email' is unsupported speculation by the Examiner, which does not amount to a finding supportive of the Examiner's obviousness conclusion."
And thus, the BPAI reversed the Examiner's 103 obviousness rejection. I agree with this decision, especially in light of the In re Zurko, 258 F.3d 1379, 1385, 59 USPQ2d 1693, 1697 (Fed. Cir. 2001) decision. On that topic, M.P.E.P. §2144.03 states: It would not be appropriate for the examiner to take official notice of facts without citing a prior art reference where the facts asserted to be well known are not capable of instant and unquestionable demonstration as being well-known ... It is never appropriate to rely solely on 'common knowledge' in the art without evidentiary support in the record, as the principal evidence upon which a rejection was based. Zurko, 258 F.3d at 1385, 59 USPQ2d at 1697 ("[T]he Board cannot simply reach conclusions based on its own understanding or experience-or on its assessment of what would be basic knowledge or common sense. Rather, the Board must point to some concrete evidence in the record in support of these findings."). What does this mean for practitioners? This decision means that when you encounter rejections that include "official notice" or "well known prior art," you must ask yourself: Is the claim element being "officially noticed" or deemed "well known" capable of instant and unquestionable demonstration as being well-known? Note the bar is quite high. In the Ex parte Chapman case, the simple idea of a customer using a phone to deliver information to a customer service rep was deemed not to pass muster. This tells me it's difficult for an Examiner to defend "official notice" and "well known prior art" rejections. My advice is to challenge "official notice" and "well known prior art" rejections and demand that the Examiner provide some evidence to support his argument, as is required under In re Zurko and M.P.E.P. §2144.03. If no such evidence is provided, you may have good grounds for an appeal.

Board of Patent Appeals Reverses Examiner's Inherency Finding
In its first decision on this Friday the 13th, the Board of Patent Appeals and Interferences (BPAI), reversed an Examiner's 103 obviousness rejection based on the Examiner's faulty inherency logic. I like this reversal because it highlights the Examiner's burden and the consequences of not meeting that burden - i.e., a win for the Applicant.
With regard to inherency, recall M.P.E.P. 2112 states that where an Applicant claims a composition in terms of a function, property or characteristic and the composition of the prior art is the same as that of the claim but the function is not explicitly disclosed by the reference, the examiner may make an inherency rejection under both 35 U.S.C. 102 and 103, expressed as a 102 or 103 rejection. See my post last year regarding the use of inherency in 103 obviousness rejections.
The case of Ex parte Smith (Appeal No. 2010-008057) involved an industrial resin. The claims recited a filler that covalently bonds with another element. The Examiner rejected the claims based on 35 U.S.C. 103(a) stating that the cited prior art discloses the same chemical structure and that the claimed covalent bonding aspect was inherent to the chemical structure disclosed in the prior art. Specifically, on the issue of the covalent bonding, the Examiner stated solely the following: "providing a workable amount of covalent bond forming coupling agents would have been obvious ... and coupling agents forms strong covalent bonds." (verbatim). That's all the Examiner had to say on the issue of inherency.
The Applicant responded with attorney argument that the cited prior art is silent on the issue of covalent bonding and that, in fact, the cited prior art could result in other types of bonding, such as ionic bonding, not necessarily covalent bonding.
The Board found: "an inherent characteristic must be inevitable, and not merely a possibility or probability. See In re Oelrich, 666 F.2d 578, 581 (CCPA 1981)." The Examiner simply concluded that Applicant's claimed chemical structure would inherently result in a covalent bond and stated nothing more. "The Examiner has not established with any evidence or provided any explanation on this record why the use of the ... agents ... in the prior art ... would inevitably, or necessarily, result in a direct covalent bond as claimed." The Board continued: "the Examiner has not satisfied the initial burden of presenting a prima facie case of obviousness." And thus, the Board reversed the Examiner's rejection.
What does this mean for practitioners? This means that you should closely analyze an Examiner's 103 obviousness rejection based on inherency to determine whether the cited art would inevitably, or necessarily, result in the Applicant's claimed device, composition or method. It is not enough for the Examiner to conclude that the cited art could potentially result in the Applicant's claimed device, composition or method. In order to meet his burden, the Examiner must cite evidence that the cited art would inevitably, or necessarily, result in the Applicant's claimed device, composition or method. If the Examiner does not meet this burden, then you may have grounds for reversal.

Quick Post: Board Reverses Examiner's Rejection in Two Sentences
In a quick decision today at the Board of Patent Appeals and Interferences (BPAI), the Board reversed an Examiner's 103 obviousness rejection in two sentences (Analysis section only). Quick work for a usually wordy Board.
The case of Ex parte Erhan (Appeal No. 2011-008127) involved a method of making fatty acid ester derivatives. The claims involved processes of production of a ketal product in combination with the hydroxyl ester product. The Examiner rejected the claims based on 35 U.S.C. 103(a) for obviousness but wrote a sparse explanation of where the claim elements were found in the prior art.
The Board began by reciting the relevant principles of law:
When determining whether a claim is obvious, an Examiner must make "a searching comparison of the claimed invention - including all its limitations - with the teachings of the prior art." In re Ochiai, 71 F.3d 1565, 1572 (Fed. Cir. 1995).
The Board finished with its Analysis section, which is reproduced below verbatim:
After reviewing the facts and arguments, we conclude that the evidence and rational set out in the rejection are insufficient to establish a prima facie case of obviousness for the method of claim 22. In particular, although the rejection identified prior art teachings concerning the production of a hydroxyl ester product, the rejection did not identify prior art teachings concerning the production of a ketal product in combination with the hydroxyl ester product, and did not resolve that difference between the prior art methods and the claimed method.
And in two sentences the Board reversed the Examiner's rejection.
What does this mean for patent practitioners?This means that much like a 35 U.S.C. 102(b) rejection, a 103 rejection must provide the equivalent of an element-by-element analysis of the elements of the claims being rejected. That is, every element of every claim must be found in the prior art cited. If you suspect that the Examiner missed, or gave little attention to, a claim element, then the Examiner is violating In re Ochiai, which may be grounds for a reversal, as in the case of Ex parte Erhan. This is in line with a previous posting I wrote about how the single most effective way to reverse a 103 obviousness-type rejection is to argue that the prior art does not disclose a claim element.

Board of Patent Appeals Decides Broadest Reasonable Interpretation of Term "On"
In a decision today at the Board of Patent Appeals and Interferences (BPAI), the Board reversed an Examiner's 103 obviousness rejection based on the unreasonableness of the Examiner's interpretation of the word "on."
The case of Ex parte Goruganthu (Appeal No. 2010-005235) involved a method of making lenses. The claims involved methods for forming solid immersion lenses on a resist film. One of the central issues was the meaning of the claim term "on." What does the term "on" mean?
The Board began by first contruing the claim term:
We begin by noting that while the term "on" is not expressly defined in the Specification, the broadest reasonable meaning of this term in its ordinary usage is a function word to indicate direct or indirect physical contact. See, e.g., pages 1574 and 1575 of WEBSTER'S THIRD NEW WORLD INTERNATIONAL DICTIONARY (G. & C. Merriam Webster, 1971) (on defined as "used as a function word to indicate contiguity or dependence."). Based on the dictionary definition of the term "on," the Board followed by construing the Applicant's claim:
Thus, the claim requires forming an array of solid immersion lenses in direct or indirect physical contact with the resist film. This is a reasonable interpretation in light of the Specification as it teaches that its solid immersion lens array 36 may be formed directly on (i.e., in direct physical
contact with) the underlying resist film.
Then, the Board went on to define what the Examiner found in the prior art:
"the Examiner maintains that Hugle teaches the disputed claim feature because Hugle' s Figure 4 illustrates a lens array 34 that is spaced above photoresist 35 (corresponding to the claimed resist film feature required by the claims) such that the lens array 34 is on the photoresist"
So the Examiner found a prior art reference that showed a lens array located over, but not touching, a photoresist. Was the Examiner correct in concluding that since the prior art showed A spaced above B, this would obviate a claim reciting A "on" B? The Board did not think so.
"Given the proper construction of the term "on" discussed above, we determine that the Examiner's interpretation of the term "on" to include a position that is spaced above the photoresist 35 is unreasonably broad. See In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997). ... nowhere does Hugle teach that the lens array is formed 'on the resist film' as required by the claims.
The Examiner simply directs us to no credible evidence to support the position that a person having ordinary skill in the art would have understood Appellants' disclosure to support this broader interpretation."
In short, the Board found that a prior art reference showing a lens array space above, but not touching, a photoresist, was not the same as, and does not obviate, a claim reciting a lens array "on" a photoresist. Consequently, the Examiner's rejection was reversed. What does this mean for patent practitioners? It means that when dealing with claims terms that comprise everyday language, you should challenge claim rejections that interpret that language too broadly. The BPAI is required to analyze claims in their broadest reasonable interpretation. In re Bigio, 381 F.3d 1320, 1324 (Fed. Cir. 2004). In cases involving everyday language that is not defined in the specification, the dictionary definition is used to construe that claim language. So get your dictionary out and make sure the Examiner didn't go beyond the dictionary definition. If he did, you may have grounds for a reversal, as in the Ex parte Goruganthu case.

Board of Patent Appeals Rejects "No Motivation to Combine" Argument Once More
Yesterday's Board of Patent Appeals and Interferences (BPAI) decision in Ex Parte Knox confirms what I've always thought about a "no motivation to combine" argument after the decision of KSR Int'l Co. v. Teleflex, Inc, - it's a narrow argument that doesn't have much punch.
The case of Ex parte Knox involved a computer program invention. The Examiner rejected the claims for being obvious in light of two prior art references - Lai and Bradshaw - under 35 U.S.C. § 103(a). Appellants presented a standard "no motivation to combine" argument.
The Board rejected this argument, first reciting case law that is often recited in BPAI decisions:
[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill." KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). The test of non-obviousness is not whether one reference can be bodily inserted into another, but, rather, what the references, when considered together, would have suggested to one of ordinary skill in the art, In re Keller, 642 F.2d 413, 425 (CCPA 1981), who is a person of ordinary creativity and not an automaton, KSR, 550 U.S. at 421, and whose inferences and creative steps we may consider, id. at 418.
If you ask me, this is pretty strong language that negates just about any "no motivation to combine" argument. The In re Keller holding appears to eliminate the need to show that two references can even be combined in a technical sense.
In light of the case law cited, the Board concluded the following:
We find that a person of ordinary skill in the art would have recognized that Bradshaw's technique of comparing first checksums with second checksums would improve Lai's file version recording ... We find that a person of ordinary skill in the art, using no more than ordinary skill and creativity, would have recognized that the calculation of a checksum ... could be performed using a checksum algorithm that is insensitive to the ordering of data, such as that taught by Lai.
The lesson learned from this case is that "no motivation to combine" arguments are not among the strongest arguments you can make at the BPAI. Seeing as the case law on combining prior art references is heavily weighted on the side of combining, I would leave this argument at the bottom of your toolbox along with the "non-analogous art" argument. Of course, every practitioner runs into tough situations at some point, and if you have nothing else, digging to the bottom of your toolbox is sometimes necessary.

Stay Away From the Non-Analogous Art Argument
Today's Board of Patent Appeals and Interferences (BPAI) decision in Ex Parte Michelle illustrates just how useless the non-analogous art argument really is. Not to beat a dead horse, since much has been written about the uselessness of this argument by my fellow patent prosecution bloggers (see Karen H.'s blog posting about this subject here), but seriously, don't use this argument anymore. I have yet to see it succeed even once.
The Ex Parte Michelle case involved a telecommunications network claim rejected under 35 U.S.C. 103(a) for being obvious. The Appellant tried his hand at the "non-analogous art" defense. The Board summarily dismissed this argument in one sentence: "Further, we find that the references Xu, Huitema and Sollee are in the same field of endeavor, involving middleboxes across multiple address realms on a network. They are thus properly combinable."
That's all the Board wrote. They didn't even offer to explain. The law on non-analogous art is rather straightforward. References within the statutory terms of 35 U.S.C. § 103 qualify as prior art for an obviousness determination only when analogous to the claimed invention. In re Clay, 966 F.2d 656, 658 (Fed. Cir. 1992). Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. In re Deminski, 796 F.2d 436, 442 (Fed. Cir. 1986); see also In re Wood, 599 F.2d 1032, 1036 (CCPA 1979) and In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004).
The moral of the story here is that the non-analogous art argument is pretty much dead and should be removed from every patent practitioner's toolbox. Continue reading "Stay Away From the Non-Analogous Art Argument" » Posted by Mark Terry | Permalink | Email This Post

The Most Effective Way of Reversing a 103 Obviousness Type Rejection
Another Losing Non-Obviousness Argument at the Board of Patent Appeals
Last week's Board of Patent Appeals and Interferences (BPAI) decision in Ex Parte Roher affirmed a Patent Examiner's 35 U.S.C. 103 obviousness rejection, thereby rejecting the Appellant's commonly used non-obvious argument. As a Patent Lawyer in Miami Florida, the Ex parte Roher decision was educational in that it highlighted a common losing non-obviousness argument.
The case of Ex Parte Roher involved packaging for hair color products. The disputed claim limitation included a recitation about alternative hair colors shown on the packaging. The Examiner asserted this claim limitation was obvious in light of the cited prior art, which was also directed to packaging for hair color products. The Appellant asserted the prior did not disclose this claim limitation and further the prior art did not hint or suggest this claim limitation. The Board rejected the Appellant's argument, and recited the well-known "ordinary creativity" argument with regard to the person of ordinary skill in the art (POSITA). Specifically, the Board stated: "Appellants' argument that [the prior art] ... does not disclose warmer, cooler and natural color fails to account for what the art would have suggested to and the creativity of one of ordinary skill in the art. KSR Int'l Co. v. Teleflex, Inc., 550 US 398, 421 (2007) ("A person of ordinary skill is also a person of ordinary creativity, not an automaton."). Clearly demonstrating variations in tone of a color or even providing different hair color blends for the consumer to view is a desirable feature as taught by [the prior art]."
This decision teaches us that a proper 35 U.S.C. 103 obviousness rejection need not disclose the exact or identical claim limitation at issue. The prior art of record may recite an element that is close to the claim limitation, as long as it would be obvious to a POSITA, who is assumed to have ordinary creativity, to make the leap to the claim limitation. This poses an additional obstacle the patent practitioner must overcome when fighting an obviousness rejection - not only must he support his argument that the prior art of record does not disclose the claim limitation at issue, he must also support his argument as to why it would NOT be obvious to a POSITA to make the logical leap to the claim limitation.

Non-Obviousness Arguments That Don't Work at the Board of Patent Appeals
Last week's Board of Patent Appeals and Interferences (BPAI) decision of Ex Parte Lim , which affirmed a Patent Examiner's 35 U.S.C. 103 obviousness rejection, teaches an important lesson - obviousness rejections must address both references - not just one. As a Miami Patent Attorney that reads BPAI decisions frequently, I'm surprised that any practitioners even try this argument anymore.
The case of Ex Parte Lim involved a mobile communications network, such as those used by cell phone providers. The Examiner issued a 35 U.S.C. 103 obviousness rejection based on two references - Lipsanen and Siren. The Appellant argued that Lipsanen did not disclose the claimed subject matter. The Appellant did not address Siren and did not address the combination of the two references.
The Board decided: "Appellants' argument [regarding] Lipsanen ... is unpersuasive as it attacks the disclosure of Lipsanen individually, rather than addressing the combination with Sirén described by the Examiner. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) and In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986).
The lesson here is a simple one. When attacking a 35 U.S.C. 103 obviousness rejection, it doesn't help to attack references individually. You must focus on the central concept behind the Examiner's rejection - the combination of the references. This means you must focus on why the combination - not the individual references - fail to disclose the claimed invention. For example, if your argument involves a claim element that is missing from the prior art, then you must argue that the combination - not the individual references - fail to disclose the claim element.

A Hidden Structural Limitation in Apparatus Claims
Today's Board of Patent Appeals and Interferences (BPAI) decision of Ex parte Nakamura et al , which reversed a Patent Examiner's 35 U.S.C. 103 obviousness rejection, was remarkable because it illustrated a method for reversing an obvioounsess rejection. As a Miami Patent Lawyer with a large patent docket, the Ex parte Nakamura was educational because it showed me where I might find a hidden structural limitation in an apparatus claim.
Ex parte Nakamura involved a box-like positioning apparatus that included various moving parts. The claim element at issue stated that the amount or distance a particular moving member can be moved was limited to a particular distance. The Examiner gave this claim element short shrift, likening it to a non-existent limitation. But the Board disagreed and found this to be a tangible, structural claim limitation. The Board stated: "as a matter of claim construction, in giving the claim terms thereof the broadest reasonable interpretation consistent with the specification, we agree with Appellants that claim 1 specifies ... thus specifying a structural configuration." See, e.g., In re Suitco Surface, Inc., 603 F.3d 1255, 1259 (Fed. Cir. 2010) (quoting In re ICON Health & Fitness, Inc., 496 F.3d 1374,1379 (Fed. Cir. 2007) (citing In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1364 (Fed. Cir. 2004)); In re Morris, 127 F.3d 1048, 1054-55 (Fed. Cir. 1997).
The moral of the story here is that when it comes to apparatus claims, every claim limitation need not be a positively recited, physical structure. Claim limitations, even structural ones, can be inferred from claim language that indicates what a physical element is capable or not capable of doing. The example in the Nakamura case is a claim limitation stating how far a physical element may be moved.

How NOT to Write a 1.132 Affidavit
Last week's Board of Patent Appeals and Interferences (BPAI) decision in Ex Parte Byers discredited a flawed 1.132 Affidavit presented by the Applicant and affirmed a Patent Examiner's 35 U.S.C. 103 obviousness rejection. As a Miami Patent Lawyer, I found the Ex parte Byers decision interesting because it showed a common pitfall when using 1.132 Affidavits.
The case of Ex parte Byers involved an online marketplace for selling healthcare products. The Applicant submitted a 1.132 Affidavit in support of its arguments and the Board found it insuficient to rebt the Examiner's prima facie case of obviousness. Specifically, the Board stated: "the conclusory statements in the Declaration are merely factual representations of his opinions."
The Board has broad discretion as to the weight to give to declarations offered in the course of prosecution. See Velander v. Garner, 348 F.3d 1359, 1371 (Fed. Cir. 2003)("[A]ccord[ing] little weight to broad conclusory statements [in expert testimony before the Board] that it determined were unsupported by corroborating references [was] within the discretion of the trier of fact to give each item of evidence such weight as it feels appropriate.") cf. Ashland Oil, Inc. v. Delta Resins & Refactories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985)("Opinion testimonytestimony rendered by experts must be given consideration, and while not controlling, generally is entitled to some weight. Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value in a validity determination." (citations omitted)). Although there is "no reason why opinion evidence relating to a fact issue should not be considered by an examiner," In re Alton, 76 F.3d 1168, 1175 n.10 (Fed. Cir. 1996). The Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations. See Velander, 348 F.3d at 1371; Ashland Oil, 776 F.2d at 294. In re American Academy of Science, 367 F.3d 1359, 1368 (Fed. Cir. 2004).
The lesson here is simple. The focus of a 1.132 Affidavit should not be opinion. It should be a recitation of the facts. Let the Examiner and the Board reach its own conclusion based on the facts recited in the 1.132 Affidavit. Otherwise, the affidavit will look like a paid endorsement of the Applicant's arguments, and it won't be given much weight.
