Civil Action 6:20-cv-256-ADA

MEMORANDUM OPINION AND ORDER

The Court considers Bumble Trading LLC’s (“Bumble” or “Defendant”) Motion for 

Summary Judgment of Invalidity Under 35 U.S.C. § 251, which contains the original patent 

requirement. After considering the briefing (Dkt. Nos. 100, 125, 148) and oral arguments, the 

Court GRANTS Bumble’s motion and finds the asserted claims 57, 63, 64, 66, 68, and 70 of U.S. 

Patent No. RE45,543 (“’543 Reissue”) and asserted claims 33, 34, 38, 45, and 46 of U.S. Patent 

No. RE47,704 (“’704 Reissue”) invalid. 

FACTUAL BACKGROUND

The ’543 Reissue and the ’704 Reissue are reissues of original U.S. Patent No. 7,080,139 

(“’139 Patent”). The ’139 Patent originally issued on July 18, 2006. The ’543 Reissue reissued 

on June 2, 2015, nearly nine years later. The ’704 Reissue reissued on November 5, 2019, over 

thirteen years later. 

Ikorongo Technology LLC and Ikorongo Texas LLC (“Plaintiffs”) sued Bumble for 

infringing the asserted claims. Neither party disputes the contents of the asserted patents or their 

file histories. No factual disputes continue to underly claim construction. Thus, no disputed 

material facts preclude summary judgment.

Original U.S. Patent No. 7,080,139

Because the specification plays an important role in meeting the original patent 

requirement, the Court provides an extended description of the ’139 Patent. The original ’139 

Patent bears the title, “Method and Apparatus for Selectively Sharing and Passively Tracking 

Communication Device Experiences,” and its abstract echoes that focus: 

The present invention includes methods and devices for passively tracking and 

selectively sharing user experiences with communication devices, including 

computers, web-enabled telephones, and PDAs. User rating or comments on their 

experiences can be captured. 

’139 Patent at Abstract (emphasis added). The detailed description states that a “common theme 

among aspects of the present invention is collecting data regarding a user’s computer usage 

experience and sharing that data.” Id. at 2:26-28. The summary states that the “present invention 

includes methods and devices for sharing communication device usage experiences, including 

computer usage experiences.” Id. at 1:30-32. “So-called ‘buddies’ identified on buddy lists of 

instant messaging products can share selected aspects of their computer usage experiences.” Id. at 

2:28-30; see also id. at 18:19-20.

The ’139 Patent contains figures showing the operation of the invention. Among these, 

figures 1, 8-11, 16, and 22-24 have the most relevance. Figure 1 provides an overview of the 

system. Toward the left, it shows “[t]racked activity may include Internet activity 120, wireless 

network location track [sic] and interaction activity 121.” Id. at 4:65-67 (emphasis added). The 

’139 Patent then immediately describes the types of activities tracked:

Activities tracked in these domains may include view, listen, rate, comment, assign 

emoticon, send, watch, download, bookmark or visit. A user views a URL, watches 

a visual presentation and listens to an audio presentation. A user visits a restaurant 

or other location. A user who views, watches, listens or visits may respond to their 

experience. A user’s response may be to rate, comment, assign an emoticon, send 

information to a buddy, download data or bookmark an item for later access.

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 2 of 18

Id. at 5:1-9 (emphasis added).

Figure 8A shows a user interface for administering a list of online buddies to share 

experiences with. Figure 8D shows an interface for selecting topics such as “Food,” “Games,” 

“Music,” and “Shopping” to share with the selected online buddies. Figures 9-11 show user 

interfaces for sharing experiences with online buddies, including what users did, what topic each 

experience relates to, details of the experience, where the experience occurred, a thumbs up or 

thumbs down, and a time of the experience. Id. at 9:16-20. The specification refers to these types 

of examples as “experiences tracked,” such as in:

The computer user experiences tracked could include viewing URLs, 

downloading files, listening to songs, viewing videos, making purchases, sending 

items from a user to their buddies, or general messaging between the user and 

buddies.

In addition to computer user experiences, mobile communication device 

locations can be tracked, using any of the technologies described above. Activities 

related to location may include visiting the location, rating, commenting on it, 

assigning an emoticon, or connecting with another buddy or buddy of a buddy at 

the location. Proximity to a location may be variation on visiting the location.

Id. at 18:53-64 (emphasis added).

The system tracks, collects, and shares user experiences using “various databases and 

combinations of databases.” Id. at 2:43-74. “One database is a visited URL database (‘VUD’)” 

that stores URLs visited by users. Id. at 2:49-51. “Another database used to practice aspects of 

the present invention is the visited location database (‘VLD’) 100B” that tracks physically visited 

locations. Id. at 3:9-10. Both the VUD and VLD store additional information describing an 

experience associated with each URL visit or physical location visit. Id. at Figure 23 steps 2355-

2366, 2:60-67, 3:10-12. 

The VUD is used for “sharing communication device and computer usage experiences. 

One type of sharing communication device user experiences is sharing computer usage 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 3 of 18

experiences, including Internet browsing experiences.” Id. at 17:41-45. “At least a portion of the 

user’s computer usage experiences are tracked and reported to a tracking server.” Id. at 18:38-39. 

“The computer user experiences tracked could include viewing URLs, downloading files, listening 

to songs, viewing videos, making purchases, sending items from a user to their buddies, or general 

messaging between the user and buddies.” Id. at 18:52-57. An entry in the VUD may include, for 

each visited URL, a rating, emoticon, title, timestamps, ratings, description, comments, and other 

types of information. Id. at 2:50-3:8; see also id. at 5:1-9. 

Like how the VUD stores a user’s experiences when browsing the internet, the “VLD stores 

similar information for locations visited by users or participants carrying portable devices.” Id. at 

3:11-12. For each visit, the VLD monitors for “activity related to a location, such as bookmarking 

a location, rating a location, adding an emoticon or comments about the location,” and adds 

information such as a “rating, location address, location description, a timestamp” or other 

information. Id. 17:3-17:25. The ’139 Patent repeatedly shows that the VLD database stores the 

“Location Address, Location Description, Location Category(s), Username(s), Timestamp(s), 

Rating(s), Emoticon(s), Comment(s) & Bookmark(s).” Id. at Figure 16 element 100, Figure 22 

element 100B, Figure 24 element 100B. “The VLD also could store geographic information 

regarding the location.” Id. at 3:26-27 (emphasis added). “Sophisticated devices may include 

circuits that determine the device’s location; these circuits may utilize GPS, DGPS, Loran or any 

other location fixing protocol. The physics of how the device and the location are associated are 

relatively unimportant; an independent service may be used to track locations visited by a user 

based on any of the protocols identified above or any other protocol.” Id. at 3:31-38. “In addition 

to computer user experiences, mobile communication device locations can be tracked, using any 

of the technologies described above.” Id. at 18:58-60 (emphasis added); see also id. at 3:12-25 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 4 of 18

(describing Bluetooth for tracking). Figure 23 shows a process related to location monitoring. The 

following passage describes the types of information stored in the VLD when various triggers 

occur:

A location network directory 2312 is accessible, which reflects location of wireless 

devices 2354 and contains information such as the devices’ location address, 

location description, a timestamp, and user ID 2358. With this information, the 

system sets the action or activity type to “visit” a location and logs an entry into a 

visited location database 2358. The system also monitors 2355 for activity related 

to a location, such as bookmarking a location, rating a location, adding an emoticon 

or comments about the location. . . . Typical activities include bookmarking 2359, 

rating, or adding an emoticon 2363 or free text comment to a location reference. 

When a location is bookmarked 2359, the system adds a bookmark flag, location 

address, location description, a timestamp and a user ID to the VLD or a buffer for 

later addition to the VLD. When a location is rated 2361, the system adds the rating, 

location address, location description, a timestamp and the user ID to the VLD or a 

buffer for later addition to the VLD. When a location is flagged with an 

emoticon 2363, the system adds the emoticon, location address, location 

description, a timestamp and the user ID to the VLD or to a buffer for later addition 

to the VLD. Similarly, when a user makes a comment on a location 2365, the 

system adds the comment, location address, location description, a timestamp and 

the user ID to the VLD or to a buffer for later addition to the VLD. For each of 

these activities, fewer or more fields may be utilized in various embodiments.

Id. at 16:67-17:26.

The ’139 Patent then describes how users can selectively share their experiences with 

buddies, for example, with friends on a “buddy list.” See, e.g., id. at 18:4-37. The parties do not 

dispute that this feature is part of the original invention and properly contained in the reissued 

claims. Still, the shared information guides the Court’s analysis. Figure 9 shows “who 981 did 

892 what 984 where 985 in what topic area 982 when 988. Ratings 986 and comments 987 also 

may be provided.” Id. at 9:17-20. As to sharing the “where,” “the name of a restaurant may be 

used instead of its Bluetooth access point address,” and a banner, logo, or icon may represent the 

location Id. at 9:41-46.

Finally, Figure 23 describes an embodiment specific to “wireless devices, such as cellular 

telephones and pagers.” Id. at 16:49-50. “It is necessary for the user to have a wireless device 

2354, which supports a location detection service. This support may be by Bluetooth, GPS or any 

other location detection technology.” Id. at 16:53-56. The system “periodically receives 

information regarding the location of the wireless device 2356.” Id. at 16:60-62. 

The original ’139 Patent contains 32 claims, including independent claims 1, 31, and 32. 

Of the independent claims, claim 1 is the longest. It relates to sharing categories of computer 

usage experiences with buddies when a user either browses URLs or visits a location. Claim 1 of 

the ’139 Patent recites:

1. A method of sharing computer user experiences, including:

communicating with a registration server to register a user, for automatic 

client-side collection of computer usage experiences for future sharing, wherein the 

computer usage experiences include one or more of browsing URLs or visiting a 

location with a location-aware device that records the visited location;

accessing one or more of the user’s messaging buddy lists and selecting one 

or more buddies with whom to share the automatically collected computer usage 

experiences;

defining categories of computer usage experiences to be shared with 

particular selected buddies;

tracking automatically on the client-side at least a portion of the user’s 

computer usage experiences and reporting the user’s computer usage experiences 

to a tracking server to be published to the particular buddies in accordance with 

their defined categories of sharing.

Claim 32 is the shortest and focuses on “sharing computer user experiences” with buddies by 

posting “the user’s visited location data.” It recites:

32. A method of sharing computer user experiences, including:

registering a user with a registration server to collect and share visited 

location data using a client-side application collected while visiting a location with 

a location-aware device that records the visited location;

accessing one or more of the user’s messaging buddy lists to identify one or 

more buddies with whom the tracking data may be shared;

defining rights of the buddies to access the visited location data;

posting at least a portion of the user’s visited location data for the buddies 

to access according to their defined rights.

The Reissue Patents RE45,543 and RE47,704

About nine years after the inventors filed the application for the original patent, and after 

a series of patent assignments, the patent’s new owners filed the applications that issued as the 

’543 Reissue and the ’704 Reissue. The applicant filed theses as broadening reissues. Dkt. No. 

125 at 5 (“the ’543 and ’704 Patents were filed as broadening reissues”). Claim 33 of the ’704 

Reissue is representative of the asserted claims in that they focus on collecting and recording 

visited “geographic location data . . . using a satellite-based location-fixing protocol” and do not 

require sharing other experience information related to the visit. Claim 70 of the ’543 Reissue does 

not require the use of a “satellite-based location-fixing protocol” and instead requires geographic 

location data collected from a “client-side application” as well as “quantifying relative influence 

of at least one user on other users.” Claim 33 of the ’704 Reissue recites:

33. A method of operation of a location-aware cellular phone device comprising:

sending registration information to a registration server from the locationaware cellular phone device;

enabling access to one or more lists of other users to identify one or more 

other users with whom visited geographic location data is to be shared;

enabling definition of access rights for the one or more other users to access 

the visited geographic location data;

collecting the visited geographic location data for geographic locations 

visited by the location-aware cellular phone device using a client-side application, 

the visited geographic location data comprising a plurality of the geographic 

locations visited by the location-aware cellular phone device, each geographic 

location visited time-stamped with a time of visit, the geographic locations visited 

automatically and passively recorded by the location-aware cellular phone device 

using a satellite-based location-fixing protocol and a detection network directory; 

and

reporting information indicating the visited geographic location data 

collected by the location-aware cellular phone device.

This reissue patent claim can be coarsely summarized as a method for tracking a user with a GPSenabled cell phone and sharing “visited geographic location data” to friends. Plaintiffs do not 

separately argue the dependent claims.

THE ORIGINAL PATENT REQUIREMENT

Settled Law

The statutory basis of the “original patent requirement” lies in 35 U.S.C. § 251(a), which 

reads:

Whenever any patent is, through error, deemed wholly or partly inoperative or 

invalid, by reason of a defective specification or drawing, or by reason of the 

patentee claiming more or less than he had a right to claim in the patent, the Director 

shall, on the surrender of such patent and the payment of the fee required by law, 

reissue the patent for the invention disclosed in the original patent, and in 

accordance with a new and amended application, for the unexpired part of the term 

of the original patent.

Thus, the reissued claims must be “for the invention disclosed in the original patent.” 35 U.S.C. 

§ 251(a). This § 251 requirement for the reissued invention to be disclosed in the original patent 

remains separate from the written description requirement of 35 U.S.C. § 112. 

Compliance with the original patent requirement is a question of law. Forum US, Inc. v. 

Flow Valve, LLC, 926 F.3d 1346, 1350–51 (Fed. Cir. 2019). A court may consider expert 

testimony to ascertain the meaning of a technical or scientific term, but expert testimony cannot 

supplant what a patent’s disclosure “actually say[s].” Forum, 926 F.3d at 1351, 1352.

The Supreme Court and Federal Circuit have interpreted this statute to mandate that the 

alleged invention of a reissue claim be “clearly and unequivocally disclose[d] . . . as a separate 

invention” in the original patent’s specification. Antares Pharma, Inc. v. Medac Pharma Inc., 771 

F.3d 1354, 1362 (Fed. Cir. 2014) (synthesizing “150 years” of Supreme Court cases) (emphasis 

added). Reissue claims violate the original patent requirement where the original specification 

“merely suggested or indicated” or “serially mentioned” the limitations within a reissued claim. 

Id. at 1359, 1363. “[I]t is not enough that an invention might have been claimed in the original 

patent because it was suggested or indicated in the specification.” Id. Rather, the “particular 

combinations” of reissue claim limitations must be disclosed in the original patent specification “in an 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 8 of 18
9

explicit and unequivocal manner.” Id. at 1363. “Whether or not the written description requirement 

of § 112 was satisfied here, . . . for § 251, it is not enough that an invention might have been claimed 

in the original patent because it was suggested or indicated in the specification. Rather, the specification 

must clearly and unequivocally disclose the newly claimed invention as a separate invention.” Id. at 

1362 (internal citations and quotations omitted).

This heightened standard protects the general public. The U.S. Patent Office may issue 

broadening reissue patents even after it publishes the issued patent and closes prosecution. When 

a reissue enlarges the scope of the patent, the patent owner “led the public to rely on the implied 

disclaimer involved in the terms of the original patent.” Miller v. Bridgeport Brass Co., 104 U.S. 

350, 356 (1881). Thus, the scope of broadening reissue claims is limited to separate inventions 

that are clearly and unequivocally disclosed in the original specification. Antares, 771 F.3d at 

1362.

Precedent includes examples of properly and improperly reissued claims. In Antares, the 

specification stated, “[a]lternatively, a push button could be located at the proximal end of the 

device,” but this “alternative” suggestion failed to rise to the level of an explicit and unequivocal 

disclosure of a safety feature of an injection device claimed on reissue when broadened from a 

claim on jet-injection devices. Id. at 1363. In contrast, the Federal Circuit held that an inventor 

properly added claims on computer-controlled rollers when the original claims covered only 

manually controlled rollers because the specification described an embodiment exactly aligned 

with the broader scope by stating that the rollers could be “raised either mechanically by the roller 

cams or electronically by the computer controlling the router. In re Amos, 953 F.2d 613, 614, 617–

19 (Fed. Cir. 1991).

Resolution of Disputed Law

The parties dispute two nuances of the original patent requirement. 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 9 of 18
10

First, Plaintiffs argue that the Court can find clear and unequivocal support for broadened 

reissued claims in the original claims. Plaintiffs appear to take this position because disputes rarely 

arise over reissued claim elements that remain identical to an original claim element. In these 

types of cases, the parties usually dispute only whether a small, broadened part of the claim meets 

the original patent requirement. But in cases such as this, where the reissued claim completely 

rewrites the original claim, the Court disagrees with Plaintiffs because “by definition in reissue the 

original claims do not disclose the invention claimed on reissue.” Antares, 771 F.3d at 1362; 35 

U.S.C. § 251 (“Whenever any patent is, through error, deemed wholly or partly inoperative or 

invalid . . . the Director shall, on the surrender of such patent and the payment of the fee required 

by law, reissue the patent for the invention disclosed in the original patent”) (emphasis added). 

That is why “the original patent requirement focuses on the original specification rather than the 

original claims.” Antares, 771 F.3d at 1362. 

Second, Bumble argues that “disparate” references to claim elements cannot be “stitchedtogether” when scattered across “all corners of the specification” to satisfy the original patent 

requirement. Dkt. 148 at 6. The Court disagrees. In evaluating the original patent requirement, 

the Court looks to the original patent in its entirety but excludes the erroneous claims. Patent 

claims frequently recite multiple steps or components, and patent specifications frequently contain 

corresponding, sequential sections written over many pages to explain the details of each claimed 

step or component. Patents often also contain an overview section stitching together these 

sequential sections of the specification into an overarching system or method. Thus, descriptions

of an original invention scattered across a specification may provide clear and unequivocal support 

for reissued claims, for example, when tied together by an overview.

ANALYSIS

The Reissue Patents Broaden the Original Claims

As a preliminary matter, the Court compares the reissued claims to the claims of the ’704 

Reissue to determine if the reissued claims broaden the scope of invention. “A broadened reissue 

claim is a claim which enlarges the scope of the claims of the patent . . . . A claim of a reissue 

application enlarges the scope of the claims of the patent if it is broader in at least one respect, 

even though it may be narrower in other respects.” MPEP § 1412.03.

Each of the reissue claims is broader in at least one respect. The reissue claims generally 

cover different aspects of the invention compared to the original claims. For example, original 

claim 32 requires “registering a user with a registration server,” but reissue claim 33 of the ’704 

Reissue does not. The parties do not meaningfully dispute that the reissue claims are broadening. 

Dkt. No. 125 at 5 (admitting “the ‘543 and ‘704 Patents were filed as broadening reissues”). 

The Court agrees with Plaintiffs that many of the disputed aspects are narrower than the 

original claims. But the law requires meeting the original patent requirement if at least one aspect

of the claim is broader, even if other aspects are narrowing. None of the cases provided by 

Plaintiffs allow the Court to exempt sections of the claim from the original patent requirement. 

Thus, the Court enforces the original patent requirement by determining if all challenged aspects 

of the reissued claims were clearly and unequivocally disclosed in the original ’139 Patent.

Parties’ Arguments

Defendant argues that the reissued claims differ substantially from the original invention

because the original ’139 Patent focuses on sharing general “experiences” with buddies, not on a 

phone for sharing only a user’s visited geographic location data. The reissue claims focus on 

collecting and sharing “visited geographic location data” using a “satellite-based location-fixing 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 11 of 18
12

protocol,” except for the distinctions noted above. Defendant argues that the original ’139 Patent

does not clearly and unequivocally disclose any embodiment that focuses on the “geographic” 

location-tracking aspect and sharing of “visited geographic location data” separate from other 

aspects related to sharing user “experiences.” 

Plaintiffs argue that the specification clearly and unequivocally supports the claims of the 

reissue patents. The specification describes tracking a user’s visit to a location (’139 Patent at 5:1-

9, 18:23-29, 18:58-64), logging the visited location in a visited location database (’139 Patent at 

3:26-27, 3:43-48, 5:1-3, 16:63-17:2), and sharing experiences with buddies (passim). Plaintiffs 

argue that the shared “experiences” include sharing geographic location data about the visits. 

Plaintiffs then argue that the specification complies with § 112, that the claims of the original ’139 

Patent provide clear and unequivocal support, and that expert testimony supports its argument. 

Resolution

The Court scoured the specification for a clear and unequivocal disclosure of the following 

aspects common to the reissue claims: (1) collecting “visited geographic location data;” (2) sharing 

such visited geographic location data (“posting at least a portion of the user’s visited location data” 

in reissue claim 33) separate and apart from sharing general experiences; and (3) using a satellitebased location-fixing protocol. The Court considered the ’139 Patent in its entirety, including the 

passages cited in Plaintiffs’ brief and the figures identified during oral argument. The specification 

fails to clearly and unequivocally disclose aspects (2) and (3) as parts of the original invention. 

As to aspect (1), the specification mentions “geographic” location data only once as data

optionally collected in addition to location information in the VLD. Id. at 3:26-27 (“The VLD 

also could store geographic information regarding the location, such as geo-coded data.”). This 

type of data collection fits with the overarching ideas of passively tracking a user by collecting 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 12 of 18
13

data. Id. at abstract, 2:26-28. Thus, this optional storage of visited geographic location data 

satisfies the original patent requirement for aspect (1) of the reissued claims.

As to aspect (2), the Court finds the specification fails to clearly and unequivocally disclose 

sharing the visited geographic location data separate and apart from sharing experiences generally

as the original invention. The separation plays an important role because it changes the 

fundamental nature of the invention from a system for sharing experiences, such as reviews of 

activities, into a tracking device that allows your friends to track your location.

The specification only mentions “geographic” location data at 3:26-27 and describes this 

geographic location data as something “also” stored alongside other experience and location 

information. Thus, the only explicit reference to “geographic” location data does not 

unequivocally support claiming storing “geographic” location data in the VLD as the original 

invention without “also” claiming storing the rest of the information in the VLD.

The “particular combinations” of reissue claim limitations, in this case geographic location 

data separate from other experience information, must be disclosed in the original patent 

specification “in an explicit and unequivocal manner.” Antares, 771 F.3d at 1363. The Court 

instead finds that the specification repeatedly and consistently describes sharing other experiencerelated information in combination with the location. ’139 Patent at Figure 9 (showing general 

experience information), Figure 16 element 100 (listing types of accompanying experience 

information), Figure 22 element 100B (listing types of accompanying experience information), 

2:49-3:12; 5:1-9, 13:36-40, 17:1-25, 17:41-45, 18:53-64. The mention of “location” or “visit” in 

a lengthy list of combinations and alternative possibilities of what is included in an “experience”

does not make it clear and unequivocal that the original invention focuses on sharing only 

“geographic” location data. See Antares, 771 F.3d at 1359 (finding that safety features “serially 

Case 6:20-cv-00256-ADA Document 204 Filed 04/12/22 Page 13 of 18
14

mentioned as part of the broader disclosure” did not amount to an explicit and unequivocal 

disclosure). Nowhere does the ’139 Patent describe a system or method that shares the specific 

combination of only geographic location data without other related experience information, as 

claimed. 

The specification’s repeated mentions of a “visit” or “location,” without more, do not serve 

as a clear and unequivocal reference to “visited geographic location data.” The question is not 

whether the words “visit” or “location” as used in the specification might encompass geographic 

location data; the question is whether that use of “visit” or “location” clearly and unequivocally 

does so. The figures show sharing a “location” or “visit” by using “useful shorthands” such as 

names, logos, and banners. Id. at figure 9, 9:39-49. Thus, any disclosure of sharing a “location” 

or “visit” may refer to sharing the name of the location or logo and fails to serve as a clear and 

unequivocal reference to “geographic” location data. 

Even when the specification does mention sharing location information, it arises in the 

context of sharing location information in addition other aspects of the experience. The abstract 

describes the original invention as “methods and devices for passively tracking and selectively 

sharing user experiences.” Id. (emphasis added). The specification repeatedly echoes this 

requirement. Id. at 3:26-27 (“The VLD also could store geographic location information regarding 

the location, such as geo-coded data”) (emphasis added), 4:65-67 (“wireless network location track

[sic] and interaction activity 121”) (emphasis added), 18:58-60 (“In addition to computer user 

experiences, mobile communication device locations can be tracked”) (emphasis added). Plaintiffs 

provide no reason for the Court to ignore these repeated statements that the original invention 

includes location information in addition to other aspects of an experience.

As to aspect (3)1 the specification does not make it clear and unequivocal that “satellitebased” location tracking is part of the original invention. The original specification does not use 

the word “satellite” at all. At best, the specification recites:

Several equivalent methods of associating a portable device with a location are 

available. Sophisticated networks may fingerprint, triangulate or otherwise locate a 

wireless device based on radio signal characteristics. Sophisticated devices may 

include circuits that determine the device’s location; these circuits may utilize GPS, 

DGPS, Loran or any other location fixing protocol. The physics of how the device 

and the location are associated are relatively unimportant; an independent service 

may be used to track locations visited by a user based on any of the protocols 

identified above or any other protocol.

Id. at 27-38. Because the specification deemed this detail “unimportant,” it cannot serve as clear 

and unequivocal support for a limitation defining the scope of the original invention. A clear and 

unequivocal statement would have instead explicitly described “satellite” based tracking as an 

important limitation instead of treating it like an unimportant variation more suited for a dependent 

claim. The mention of “GPS” and “DGPS” as part of a serial list of suggestions does not amount 

to an explicit and unequivocal disclosure that the scope of the original invention is limited to all 

“satellite-based location-fixing protocol[s]” as recited in reissue claim 33, at the exclusion of 

Bluetooth, triangulation, radio signal, Loran, and other location fixing protocols. See Antares, 771 

F.3d at 1363 (finding that safety features “serially mentioned as part of the broader disclosure” did 

not amount to an explicit and unequivocal disclosure). What is “necessary” in the original 

invention is a “wireless device 2354, which supports a location detection service. This support 

may be Bluetooth, GPS or any other location detection technology.” ’139 Patent at 16:53-56.

Public policy supports the Court’s conclusions. For about nine and thirteen years for the 

’543 Reissue and ’704 Reissue, respectively, the patent owner led the public to rely on the implied 

1 Not applicable to the ’543 Reissue, claim 70.

disclaimer involved in the terms of the original patent. Miller, 104 U.S. at 356. The original ’139 

Patent put the public on notice of an invention related to sharing experiences, generally, with 

buddies. A fair reading did not put the public on notice that the claims should have been corrected 

to cover a satellite-based, geographic location tracking invention for sharing one’s visited 

geographic location data with buddies, without including the sharing of related experience 

information.

Plaintiffs’ Remaining Arguments Rejected

The cited cases do not support Plaintiffs’ arguments. In Amos, “the exact embodiment 

claimed on reissue was expressly disclosed in the specification.” Antares, 771 F.3d at 1363 

(explaining the holding in Amos, 953 F.2d at 617–19). Here, the exact embodiment with “the 

geographic locations visited automatically and passively recorded by the location-aware cellular 

phone device using a satellite-based location-fixing protocol” as recited in reissue claim 33 

remains missing from the specification. Additionally, the use of “geographic” location data is 

mentioned only in addition to other experience information, and the scope of all “satellite-based” 

location fixing protocols remains missing entirely. 

In Antares, the “original claims [were] significantly different in scope and coverage than 

the asserted claims.” 771 F.3d at 1362. Thus, the Federal Circuit looked to the specification and 

found that “the original specification does not adequately disclose the later-claimed safety 

features” because “[t]he specification discussed only one invention: a particular class of jet 

injectors.” Id. “Although safety features were mentioned in the specification, they were never 

described separately from the jet injector.” Id. at 1363. Here, the Court finds that the original ’139 

Patent specification discloses two class of inventions: experience sharing systems and methods for 

internet activity and experience sharing systems and methods for visits, but not geographic location

tracking devices. Although the original ’139 Patent mentions “GPS” based tracking in the 

specification as part of tracking users for sharing their general experiences when visiting locations, 

tracking users using any “satellite-based” tracking protocol is never described at all, much less 

described separately from generally sharing experiences at a particular location. 

Plaintiffs’ other arguments remain unpersuasive. Plaintiffs argued that original claim 32 

supports the reissued claims. The Court did not look to original claim 32 of the ’139 Patent to find 

the invention disclosed in the original patent because “by definition in reissue the original claims 

do not disclose the invention claimed on reissue. Thus, we must look to the specification.” Antares, 

771 F.3d at 1362. Plaintiff also urged the Court to consider supporting expert testimony. The 

Court considered it but found the testimony of Plaintiffs’ expert unnecessary because expert 

testimony cannot supplant what a patent’s disclosure actually says. Forum, 926 F.3d at 1351, 

1352. Plaintiffs argued that the original ’139 Patent undisputedly provides § 112 written 

description support for the claims. But “[w]hether or not the written description requirement of 

§ 112 was satisfied here, . . . for § 251, it is not enough that an invention might have been claimed 

in the original patent because it was suggested or indicated in the specification. Rather, the 

specification must clearly and unequivocally disclose the newly claimed invention as a separate 

invention.” Antares, 771 F.3d at 1362 (internal citations and quotations omitted).

CONCLUSION

It is ORDERED that Defendant Bumble Trading LLC’s Motion for Summary Judgment of 

Invalidity Under 35 U.S.C. § 251 (Original Patent Requirement) is GRANTED. Accordingly, under 

35 U.S.C. § 251, asserted claims 57, 63, 64, 66, 68, and 70 of U.S. Patent No. RE45,543, and asserted 

claims 33, 34, 38, 45, and 46 of U.S. Patent No. RE47,704, are invalid.
