The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA  35 U.S.C. 102 and 103 (or as subject to pre-AIA  35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA  to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 15-17 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lemen (US 20180141376 A1).

Allowable Subject Matter
Claims 1-14, and 19-20 are allowed.
Claim 18 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:  the prior art of record does not show nor disclose the combination set forth in claim 1, 18, and 19.
In particular for claim 1, the prior art of record does not disclose nor render obvious a cover apparatus for a bearing comprising a knob protruding from the second side of the body opposite the first side in combination with the other claim limitations.
In particular for claim 18, the prior art of record does not disclose nor render obvious the cover assembly of claim 15, wherein the first seating surface engages a first side of an outer ring of the bearing, the second seating surface engages a first side of an inner ring of the bearing, and the first protrusion is at least partially inserted in the bore of the bearing when the first cover is coupled to a first side of the bearing in combination with the other claim limitations.
In particular for claim 19, the prior art of record does not disclose or render obvious a method of forming a cover for a bearing, the method comprising a grip protruding from the second side of the body in combination with the other claim limitations.
The bearing covers in the prior arts shows the cover having a protrusion toward or outward the bearing but none of them show any sort of grip or knob on the cover.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Scheller (US 5711617 A) discloses a dust cap for a bearing assembly.
Waskiewicz (US 5711618 A) discloses another dust cap for a bearing assembly.
Gingrich (US 5816711 A) discloses a bearing assembly with an end cap.
Yamashita (US 6193418 B1) discloses a safety end cap for rotary bearing.
Downey et al. (US 6283635 B1) discloses a bearing housing and cover assembly.

APPLICANT REBUTTAL: REMARKSThe Office action of June 2, 2025 has been considered. By way of this response, claims 15 and 18 have been amended. No new matter has been added. This application is in condition for allowance and favorable reconsideration is respectfully requested.Allowed Claims The Applicant notes with appreciation the indication that claims 1-14 and 19-20 are in condition for allowance.Allowable Subject Matter Claim 18 would be allowable if rewritten in independent claim to include the subject matter if its base claim and any intervening claim(s).35 U.S.C. §102 Rejections Claims 15-17 were rejected under 35 U.S.C. §102, as allegedly being anticipated by Lemen (US 20180141376). All rejections are respectfully traversed.Claim 15 sets forth a first cover to couple to a first side of a bearing, the first cover including a first protrusion, a first seating surface and a second seating surface, the first seating surface to engage a first side of an outer ring of the bearing. Claim 15 is allowable over Lemen.Lemen mentions an outboard guard 321 and an outboard retainer cap 320, where "the retainer cap 320 includes an outboard alignment protrusion 337 that contacts an inner surface 338 (see FIG. 6) of the outboard bearing cone 317"..."an engagement portion 339 and a retaining flange 340, where the retaining flame 340 engages with an outboard bearing protector portion of the outboard guardd 321." (Lemen, ¶53)(emphasis added). Because the retaining flange 340 of the outboard retainer cap 320 engages the outboard guard 321, Lemen fails to teach or suggest a first cover to couple to a first side of a bearing, the first cover including a first protrusion, a first seating surface and a second seating surface, the first seating surface to engage a first side of an outer ring of the bearing, as set forth by claim 15. Thus, Lemen fails to establish a prima facie case of anticipation against claim 15. Accordingly, claim 15 and all claims that depend therefrom are in condition for allowance.CONCLUSIONIn general, the official action makes various statements regarding the claims and the cited references that are now moot in light of the above. Thus, the applicants will not address such statements at the present time. However, the applicants expressly reserve the right to challenge such statements in the future should the need arise (e.g., if such statements should become relevant by appearing in a rejection of any current or future claim).The Commissioner is hereby authorized to refund any overpayment and charge any deficiency in the amount paid in connection with this paper or any additional fees which may be required during the pendency of this application under 37 CFR 1.16 or 1.17 to Deposit Account No. 50-2455. In addition, if a petition for an extension of time under 37 CFR 1.136(a) is necessary to maintain the pendency of this case and is not otherwise requested in this case, the assignee requests that the Commissioner consider this paper to be a petition for an extension of time and authorizes the Commissioner to charge the fee as set forth in 37 CFR 1.17(a) corresponding to the needed extension of time to Deposit Account No. 50-2455.Respectfully submitted on this date June 12, 2025.HANLEY, FLIGHT & ZIMMERMAN, LLC
