There are generally two types of double patenting rejections. One is the same invention type or "statutory" double patenting rejection based on 35 U.S.C. 171 which states in the singular that an inventor may obtain "a patent." The second is the "nonstatutory" double patenting rejection based on a judicially created doctrine grounded in public policy and which is primarily intended to prevent prolongation of the patent term by prohibiting claims in a second patent not patentably distinct from claims in a first patent.
The doctrine of nonstatutory double patenting also seeks to prevent the possibility of multiple suits against an accused infringer by different assignees of patents claiming patentably indistinct variations of the same invention. In re Van Ornum, 686 F.2d 937, 944-48, 214 USPQ 761, 767-70 (CCPA 1982). The submission of a terminal disclaimer in compliance with 37 CFR 1.321(b) to overcome a double patenting rejection ensures that a patent owner with multiple patents claiming obvious variations of one invention retains all those patents or sells them as a group. Van Ornum, 686 F.2d at 944-45, 214 USPQ at 767. Nonstatutory double patenting includes rejections based on anticipation, a one-way determination of "obviousness," or a two-way determination of "obviousness." It is important to note that the "obviousness" analysis for nonstatutory double patenting is "similar to, but not necessarily the same as, that undertaken under 35 U.S.C. 103." In re Braat, 937 F.2d 589, 592-93, 19 USPQ2d 1289, 1292 (Fed. Cir. 1991) (citing In re Longi, 759 F.2d 887, 892 n.4, 225 USPQ 645, 648 n.4 (Fed. Cir. 1985)); Geneva Pharmaceuticals, 349 F.3d 1373, 1378 n.1, 68 USPQ2d 1865, 1869 n.1 (Fed Cir. 2003). In addition, nonstatutory double patenting also includes rejections based on the equitable principle against permitting an unjustified timewise extension of patent rights. See In re Schneller, 397 F.2d 350, 158 USPQ 210 (CCPA 1968); see also MPEP § 804, subsection II.B.3.
Charts in MPEP § 804 outline procedure for handling all double patenting rejections.
Double patenting rejections are based on a comparison of the claims in a patent and an application or between two applications which have at least one common inventor, common applicant, and/or are commonly assigned/owned or non-commonly assigned/owned but subject to a joint research agreement as set forth in 35 U.S.C. 102(c) or in pre-AIA 35 U.S.C. 103(c)(2) and (3). Notably, 35 U.S.C. 171 specifically states that "a patent" may be obtained if certain conditions are met; this use of the singular makes it clear that only one patent may issue for a design and is the basis for the statutory double patenting rejections.
Determining if a double patenting rejection is appropriate involves answering the following inquiries: Is the same design being claimed twice? If the answer is yes, then a rejection under 35 U.S.C. 171 should be made on the grounds of "same invention" type or statutory double patenting. If not, are the designs directed to patentably indistinct variations of the same inventive concept? If the answer is yes, then a rejection based on the nonstatutory double patenting should be made.
Double patenting rejections are based on a comparison of claims. In double patenting rejections, the disclosure of the patent or application may be relied upon only to define the claim. While there is a direct correlation between the drawings in a design application and the claim, examiners must be aware that no such correlation is necessary in a utility application or patent. Several utility patents may issue with the identical drawing disclosure but with claims directed to different inventions. So any consideration of possible double patenting rejections between a utility application or patent with a design application cannot be based on the utility drawing disclosure alone. See Anchor Hocking Corp. v. Eyelet Specialty Co., 377 F. Supp. 98, 183 USPQ 87 (D. Del. 1974). The examiner must be able to recreate the design claimed from the utility claims without reliance on the drawings.
If a provisional double patenting rejection (nonstatutory or statutory) is the only rejection remaining in two conflicting applications, the examiner should consult MPEP § 1490, subsection VI.D to determine which, if any, of the provisional double patenting rejections should be withdrawn.
A provisional double patenting rejection will be converted into a double patenting rejection when the first application, which is the basis for the rejection, publishes as an application publication or issues as a patent. If more than two applications conflict with each other and one is allowed, the remaining applications should be cross rejected against the others as well as the allowed application. For this type of rejection to be appropriate, there must be either at least one inventor in common, common applicant, or a common owner/assignee. If the claims in copending design applications or a design patent and design applications have a common assignee but different inventive entities, anticipation and/or obviousness rejections based on the other application or patent as prior art under 35 U.S.C. 102(a)(2) or pre-AIA 35 U.S.C. 102(e), (f) and (g), as applicable, must be considered in addition to the double patenting rejection. See MPEP § 804, § 21.6, § 21.7, § 21.8, and § 21.4.
A design - design statutory double patenting rejection based on 35 U.S.C. 171 prevents the issuance of a second patent for a design already patented. For this type of double patenting rejection to be proper, identical designs with identical scope must be twice claimed. See In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993). A design - utility "same invention" double patenting rejection is based on judicial doctrine as there is no statutory basis for this rejection because neither 35 U.S.C. 101 nor 35 U.S.C. 171 can be applied against both claims. See In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A "same invention" type double patenting rejection, whether statutory or nonstatutory, cannot be overcome by a terminal disclaimer. See In re Swett, 145 F.2d 631, 172 USPQ 72 (CCPA 1971).
The claim is rejected under 35 U.S.C. 171 on the ground of double patenting since it is claiming the same design as that claimed in United States Design Patent No. .
Form paragraph 15.23.02 should follow all "same invention" type double patenting rejections.
The claim is provisionally rejected under 35 U.S.C. 171 on the ground of double patenting since it is claiming the same design as that claimed in copending Application No. . This is a provisional double patenting rejection since the conflicting claims have not in fact been patented.
The claim is rejected under the judicially created doctrine of double patenting as being directed to the same invention as that set forth in claim  of United States Patent No. . See In re Thorington, 418 F.2d 528,163 USPQ 644 (CCPA 1969).
The claim is provisionally rejected under the judicially created doctrine of double patenting as being directed to the same invention as that set forth in claim  of copending Application No. . See In re Thorington, 418 F.2d 528,163 USPQ 644 (CCPA 1969).
This is a provisional double patenting rejection because the claims have not in fact been patented.
Applicant is advised that a terminal disclaimer may not be used to overcome a "same invention" type double patenting rejection. In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969); MPEP § 804.02.
This form paragraph should follow all "same invention" type double patenting rejections.
A rejection based on nonstatutory double patenting is based on a judicially created doctrine grounded in public policy so as to prevent the unjustified or improper timewise extension of the right to exclude granted by a patent. See In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993). A double patenting rejection also serves public policy when it prevents the possibility of multiple suits against an accused infringer by different assignees of patents claiming patentably indistinct variations of the same invention. In re Van Ornum, 686 F.2d 937, 944-48, 214 USPQ 761, 767-70 (CCPA 1982).
A nonstatutory double patenting rejection applies to claims directed to the same inventive concept but with different appearances or differing scope that are patentably indistinct from each other. Nonstatutory categories of double patenting rejections which are not the "same invention" type may be overcome by the submission of a terminal disclaimer.
In determining whether a nonstatutory double patenting rejection is appropriate, the examiner must compare the overall appearance of the claimed design in the application with the overall appearance of the claimed design in the conflicting application or patent. The claim in the patent or conflicting application must be considered as a whole, i.e., the elements of the claimed design of the reference are not considered individually as they may be when establishing a prima facie case of anticipation under 35 U.S.C. 102 or obviousness under 35 U.S.C. 103. See MPEP § 804, subsection II.B. (information on the analysis for nonstatutory double patenting rejections). For example, in an obviousness analysis, after the factual inquiries mandated under Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), have been made (as with a rejection under 35 U.S.C. 103, the examiner must then determine whether the results of the inquiries support a conclusion nonstatutory double patenting. To establish nonstatutory double patenting under an obviousness analysis: (A) the conflicting design claims must have overall appearances with basically the same design characteristics; and (B) the differences between the two designs must be insufficient to patentably distinguish one design from the other. Differences may be considered patentably insufficient when they are de minimis or obvious to a designer of ordinary skill in the art. While the conflicting application or patent (if less than a year older than the application) used to establish nonstatutory double patenting is not considered "prior art," the principle involved is basically the same. See In re Zickendraht, 319 F.2d 225, 138 USPQ 22 (CCPA 1963)(see concurring opinion of Judge Rich).
(C) No terminal disclaimer has been filed.
This kind of nonstatutory double patenting rejection in designs will occur between designs which may be characterized as a combination (narrow claim) and a subcombination/element thereof (broad claim). See MPEP § 1504.05, subsection II, B. If the designs are patentably indistinct and are directed to the same inventive concept the examiner must determine whether the subject matter of the narrower claim is fully disclosed in and covered by the broader claim of the reference. If the reference does not fully disclose the narrower claim, then a double patenting rejection should not be made. The additional disclosure necessary to establish that the applicant was in possession of the narrower claim at the time the broader claim was filed may be in a title or descriptive statement as well as in a broken line showing in the drawings. If the broader claim of the reference does not disclose the additional subject matter claimed in the narrower claim, then applicant could not have claimed the narrower claim at the time the application with the broader claim was filed and a rejection under nonstatutory double patenting would be inappropriate.
A nonstatutory double patenting rejection may be made between a patent and an application or provisionally between applications. Such rejection over a patent may only be necessary if the patent issued less than a year before the filing date of the application. If the patent is more than a year older than the application, the patent is considered to be "prior art" under 35 U.S.C. 102(a)(1) or pre-AIA 35 U.S.C. 102(b) which may be applied in an anticipation or obviousness rejection as applicable. The purpose of a terminal disclaimer is to obviate a nonstatutory double patenting rejection by removing potential harm to the public by issuing a second patent. See MPEP § 804.
If double patenting is raised between a patent and a continuing application, examiners are reminded that this ground of rejection can only be made when the filing of the continuing application is voluntary and not the direct, unmodified result of restriction requirement under 35 U.S.C. 121. See MPEP § 804.01.
Examiners should particularly note that a design-design nonstatutory double patenting rejection does not always have to be made in both of the conflicting applications. For the most part, these rejections will be made in each of the conflicting applications; but, if the rejection is only appropriate in one direction, it is proper to reject only one application. The criteria for determining whether a one-way distinctness determination is necessary or a two-way distinctness determination is necessary is set forth in MPEP § 804, subsection II.B.2(b) and (c). However, in design-utility situations, a two-way distinctness determination is necessary for the rejection to be proper. See In re Dembiczak, 175 F.3d 994, 50 USPQ2d 1614 (Fed. Cir. 1999).
The following form paragraphs may be used in making a nonstatutory double patenting rejection. Explanation should be provided in the appropriate brackets.
¶ 15.24.06 Basis for Nonstatutory Double Patenting, "Heading Only"
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the "right to exclude" granted by a patent and to prevent possible harassment by multiple assignees. See In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the conflicting application or patent is shown to be commonly owned with this application. See 37 CFR 1.131(c). A registered attorney or agent of record may sign a terminal disclaimer.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/forms/. The filing date of the application will determine what form should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission.
