MPEP § 1302.14
*****
One of the primary purposes of 37 CFR 1.104(e) is to improve the quality and reliability of issued patents by providing a complete file history which should clearly reflect, as much as is reasonably possible, the reasons why the application was allowed. Such information facilitates evaluation of the scope and strength of a patent by the patentee and the public and may help avoid or simplify litigation of a patent.
It should be noted that the setting forth of reasons for allowance is not mandatory on the examiner’s part. However, in meeting the need for the application file history to speak for itself, it is incumbent upon the examiner in exercising their responsibility to the public, to see that the file history is as complete as is reasonably possible.
When an application is finally acted upon and allowed, the examiner is expected to determine, at the same time, whether the reasons why the application is being allowed are evident from the record.
Prior to allowance, the examiner may also specify allowable subject matter and provide reasons for indicating such allowable subject matter in an Office communication.
In determining whether reasons for allowance should be recorded, the primary consideration lies in the first sentence of 37 CFR 1.104(e) which states:
If the examiner believes that the record of the prosecution as a whole does not make clear his or her reasons for allowing a claim or claims, the examiner may set forth such reasoning. (Emphasis added).
In most cases, the examiner’s actions and the applicant’s replies make evident the reasons for allowance, satisfying the "record as a whole" proviso of the rule. This is particularly true when applicant fully complies with 37 CFR 1.111(b) and (c) and 37 CFR 1.133(b). Thus, where the examiner’s actions clearly point out the reasons for rejection and the applicant’s reply explicitly presents reasons why claims are patentable over the reference, the reasons for allowance are in all probability evident from the record and no statement should be necessary. Conversely, where the record is not explicit as to reasons, but allowance is in order, then a logical extension of 37 CFR 1.111 and 1.133 would dictate that the examiner should make reasons of record and such reasons should be specific.
Where specific reasons are recorded by the examiner, care must be taken to ensure that statements of reasons for allowance (or indication of allowable subject matter) are accurate, precise, and do not place unwarranted interpretations, whether broad or narrow, upon the claims. The examiner should keep in mind the possible misinterpretations of their statement that may be made and its possible effects. Each statement should include at least (1) the major difference in the claims not found in the prior art of record, and (2) the reasons why that difference is considered to define patentably over the prior art if either of these reasons for allowance is not clear in the record. The statement is not intended to necessarily state all the reasons for allowance or all the details why claims are allowed and should not be written to specifically or impliedly state that all the reasons for allowance are set forth. Where the examiner has a large number of reasons for allowing a claim, it may suffice to state only the major or important reasons, being careful to so couch the statement. For example, a statement might start: "The primary reason for the allowance of the claims is the inclusion of the limitation in all the claims which is not found in the prior art references," with further amplification as necessary.
Stock paragraphs with meaningless or uninformative statements of the reasons for the allowance should not be used. It is improper to use a statement of reasons for allowance to attempt to narrow a claim by providing a special definition to a claim limitation which is argued by applicant, but not supported by a special definition in the description in cases where the ordinary meaning of the term in the prior art demonstrates that the claim remains unpatentable for the reasons of record, and where such claim narrowing is only tangential to patentability. Cf. Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., 535 U.S. 722, 741, 62 USPQ2d 1705, 1714 (2002). The statement of reasons for allowance by the examiner is intended to provide information equivalent to that contained in a file in which the examiner’s Office actions and the applicant’s replies make evident the examiner’s reasons for allowing claims.
Examiners are urged to carefully carry out their responsibilities to see that the application file contains a complete and accurate picture of the Office’s consideration of the patentability of the application.
Under 37 CFR 1.104(e), the examiner must make a judgment of the individual record to determine whether or not reasons for allowance should be set out in that record. These guidelines, then, are intended to aid the examiner in making that judgment. They comprise illustrative examples as to applicability and appropriate content. They are not intended to be exhaustive.
Most instances when the examiner finds a need to place in the file a statement of the reasons for allowing a claim or claims will come at the time of allowance. In such cases, the examiner should (a) check the appropriate box on the form PTOL-37 and (b) attach thereto a paper containing the examiner's statement of reasons for allowance. The paper should identify the application number and be clearly labeled "Statement of Reasons for Allowance." It should also specify that comments may be filed by the applicant on the statement and should preferably be submitted with the payment of the issue fee so as not to delay processing of the application and in any event must be filed no later than payment of the issue fee.
Form paragraph 13.03 may be used for this purpose.
The following is an examiner’s statement of reasons for allowance: [1]
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled "Comments on Statement of Reasons for Allowance."
1. Do not use this form paragraph in reexamination proceedings, see form paragraph 22.16.
2. In bracket 1, provide a detailed statement of the reason(s) certain claim(s) have been indicated as being allowable or as containing allowable subject matter.
A statement may be sent to applicant with other communications, where appropriate, but should be clearly labeled as a "Statement of Reasons for Allowance" and contain the data indicated above.
Form paragraph 13.03.01 may be used to specify the reasons for indicating allowable subject matter in a communication prior to allowance.
The following is a statement of reasons for the indication of allowable subject matter: [1]
1. This form paragraph is for use in an Office action prior to allowance of the application. Use form paragraph 13.03 in the Notice of Allowability.
2. In bracket 1, provide a detailed statement of the reason(s) certain claim(s) have been indicated as being allowable or as containing allowable subject matter.
The examiner’s statement of reasons for allowance is an important source of prosecution file history. See Zenith Labs., Inc. v. Bristol-Myers Squibb Co., 19 F.3d 1418, 30 USPQ2d 1285 (Fed. Cir. 1996). The examiner’s statement of reasons for allowance is the personal opinion of the examiner as to why the claims are allowable. The examiner’s statement should not create an estoppel. Only applicant’s statements should create an estoppel. The failure of applicant to comment on the examiner’s statement of reasons for allowance should not be treated as acquiescence to the examiner’s statement. See Salazar v. Procter & Gamble Co., 414 F.3d 1342, 1347, 75 USPQ2d 1369, 1373 (Fed. Cir. 2005). Any inferences or presumption are to be determined on a case-by-case basis by a court reviewing the patent, the USPTO examining the patent in a reissue application or a reexamination proceeding, the Patent Trial and Appeal Board reviewing the patent in an interference or derivation proceeding, etc. Applicant may set forth his or her position if he or she disagrees with the examiner’s reasons for allowance.
Comments filed by the applicant on the examiner’s statement of reasons for allowance, should preferably be submitted no later than the payment of the issue fee, to avoid processing delays. Such submissions should be clearly labeled "Comments on Statement of Reasons for Allowance." Comments will be entered in the application file by the Office of Data Management with an appropriate document code in the file wrapper.
The application file generally will not be returned to the examiner after the entry of such comments made by applicant on the examiner’s statement of reasons for allowance. Therefore, the absence of an examiner’s response to applicant's comments does not mean that the examiner agrees with or acquiesces in the reasoning of such comments. See 37 CFR 1.104(e). While the examiner may review and comment upon such a submission, the examiner has no obligation to do so.
