Office Action

§101
DETAILED ACTION 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 . Status of Claims Claims 1, 8-15, 17-18, 20, 22-27 are pending and examined on the merits. Information Disclosure Statement The references cited by applicants in the information disclosure statements filed from 3/7/2025 to 4/9/2026 have been made of record. Examiner has considered the voluminous references to the best of her ability. While the statements filed do not comply with the guidelines set forth in MPEP 2004 regarding both the number of references cited and the elimination of clearly irrelevant art and marginally cumulative information, compliance with these guidelines is not mandatory. Furthermore, 37 CFR 1.97 and 1.98 does not require that the information be material; rather, they allow for submission of information regardless of its pertinence to the claimed invention. Also, there is no requirement to explain the materiality of the submitted references. However, the cloaking of a clearly relevant reference by inclusion in a long list of citations may not comply with Applicant’s duty of disclosure. See Penn Yan Boats, Inc. v. Sea Lark boats Inc., 359 F. Supp. 948, aff’d 479 F. 2d. 1338. Applicant is advised that the MPEP states the following with respect to large information disclosure statements: Although a concise explanation of the relevance of information is not required for English language information, applicants are encouraged to provide a concise explanation of why the English-language information is being submitted. Concise explanations (especially those that point out the relevant pages and lines) are helpful to the Office, particularly where documents are lengthy and complex and applicant is aware of a section that is highly relevant to patentability or where a large number of documents are submitted and applicant is aware that one or more is highly relevant to patentability. MPEP § 609.04(a)(III). This statement is in accord with dicta from Molins PLC v. Textron, Inc., 48 F.3d 1172 (Fed. Cir. 1995), states that forcing the Examiner to find “a needle in a haystack” is “probative of bad faith.” Id. at 1888. This case presented a situation where the disclosure was in excess of 700 pages and contained more than fifty references. Id. 1888. The MPEP provides more support for this position. In a subsection entitled “Aids to Compliance With Duty of Disclosure,” item thirteen states: It is desirable to avoid the submission of long lists of documents if it can be avoided. Eliminate clearly irrelevant information and marginally pertinent cumulative information. If a long list is submitted, highlight those documents which have been specifically brought to Applicant’s attention and/or are known to be of the most significance. See Penn Yan Boats, Inc. v. Sea Lark Boats, Inc., 359 F.Supp 948 (S.D. Fla. 1972) aff’d 479 F.2d 1338 (5th Cir 1974). See also MPEP § 2004. Therefore, it is recommended that if any information that has been cited by Applicants in the previous disclosure statement is known to be material for patentability as defined by 37 CFR 1.56, Applicant should present a concise statement as to the relevance of that/those particular documents therein cited. Drawings The drawings are objected to as failing to comply with 37 CFR 1.84(p)(4) because reference characters "802" and "804" (see Figs. 24a & 24b) have both been used to designate urine inlet (see [0217] of PGPub of current Application, namely US 2025/0161627). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 1, 8-15, 17-18, 20, 22-27 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1-18, respectively, of prior U.S. Patent No. 12,539,390. This is a statutory double patenting rejection. Claim Objections Claim 1 is objected to because of the following informalities: Re Claim 1, at the end of the claim, “wherein the anti-removal structure is located on the opposite side of the first urine inlet to the inlet” should be “wherein the anti-removal structure is located on the opposite side of the first urine inlet to the inlet protector”. Appropriate correction is required. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. WO 2018/200643 discloses a urinary catheter having multiple umbrella-shaped shields disposed along a distal tip of the catheter.
