Office Action

§DP
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Double Patenting 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. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); 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); 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) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) 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. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1-10 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent Nos. 10,960,273; 11,583,737; and 11,992,734 in view of Shear 2007/0049417 and Llewellyn et al. 10,926,141. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claim 1 does not substantially change the scope of the previously patented claims. In the instant claims the rear trough is designed to differ in shape and relative width at its ends from the forward trough where the prior patents called for the relative width of the rear channel to be 1.5-2.5 times wider. Shear teaches that it would have been obvious to have made the ends of the troughs on the earlier patent wider in order to alleviate stress and Llewellyn teaches at [0030] that the COR can be controlled by modifying the number and dimensions of multiple slots that are the same width in the center as shown in fig. 4. To have designed the troughs of the prior patents to be equal in the center and wider on the ends of the rear trough would have been obvious in order to design the COR of the face as desired at the intended points of impact. Conclusion No art rejection is made with respect to Llewellyn at least for the reasons found in 17/301,154, non-final action dated 3/30/2022 where it noted that while he does discuss thicknesses general wall thicknesses in the forward and rear walls of the trough he does not discuss them relative to one another no recited only with respect to only the forward trough. Any inquiry concerning this communication or earlier communications from the examiner should be directed to William Pierce whose telephone number is (571)272-4414 and E-mail address is bill.pierce@USPTO.gov. For emergency assistance, supervisory assistance can be obtained with Melba Bumgarner at (571)272-4709. If attempts to reach the examiner by telephone are unsuccessful, communication via email at the above address may be found more effective. Where current PTO internet usage policy does not permit an examiner to initiate communication via email, such are at the discretion of the applicant. However, without a written authorization by applicant in place, the USPTO will not respond via Internet e-mail to any Internet correspondence which contains information subject to the confidentiality requirement as set forth in 35 U.S.C. 122. A paper copy of such correspondence will be placed in the appropriate patent application. The following is a sample authorization form which may be used by applicant: “Recognizing that Internet communications are not secure, I hereby authorize the USPTO to communicate with me by responding to this inquiry by electronic mail. I understand that a copy of these communications will be made of record in the application file.” The fax phone number for the organization where this application or proceeding is assigned is 571-273-8300.
