Prior art

To identify the most relevant prior art for US patent 11731682 and analyze its potential to anticipate claims, I would need to access the full patent document and its cited references. As a large language model, I do not have the ability to directly search the USPTO database in real-time or analyze patent claims for anticipation under 35 U.S.C. § 102. The provided search results indicate that the USPTO offers a "Patent Public Search" tool for this purpose.

However, based on the information provided in the original prompt (the full patent text for US11731682B2), I can extract the list of "Prior art keywords" and "Priority claimed from" patents. This information is crucial for understanding the patent's context and identifying potential prior art.

From the provided text for US11731682B2, the following "Prior art keywords" are listed:

• stroller
• seat
• seat attachment
• attachment
• frame

The patent also lists several "Priority claimed from" applications:

• US12/633,751 (Priority date: 2009-12-08)
• US14/261,558 (Priority date: 2014-04-25), which is related to US8955869B2
• US16/903,292 (Priority date: 2020-06-16), which is related to US11731682B2 (this patent itself, so not prior art)
• US17/876,492 (Priority date: 2022-07-28), which is related to US11577771B2
• US17/877,323 (Priority date: 2022-07-29), which is related to US11505231B1
• US18/051,053 (Priority date: 2022-10-31), which is related to US11878729B2
• US18/448,417 (Priority date: 2023-08-11), which is related to US12275449B2
• US18/534,146 (Priority date: 2023-12-08), which is related to US20240174281A1
• US19/081,266 (Priority date: 2025-03-17), which is related to US20250214641A1

To provide a full prior art analysis, including detailed descriptions and claim anticipation, I would need to perform the following steps for each relevant cited patent:

1. Retrieve the full text of each cited patent.
2. Carefully read and understand the claims of US11731682.
3. Compare the teachings of each cited patent against each claim of US11731682 to determine if all elements of a claim are present in a single prior art reference (anticipation under 35 U.S.C. § 102).

Without direct access to the USPTO search functionality and the ability to retrieve and analyze the full text of cited patents, I can only list the potential prior art identified in the provided text.

Based on the "Priority claimed from" section, the following are direct parent applications or related patents that could be considered for prior art analysis, given their earlier priority dates compared to US11731682's filing date of 2020-06-16 and publication date of 2023-08-22:

• US12/633,751

  • Publication/Filing Date: Priority claimed from 2009-12-08.
  • Brief Description: This is a parent application. The full patent text states that US11731682 is a continuation of Ser. No. 15/912,901, which is a continuation of Ser. No. 15/225,326 (US Pat. No. 9,944,305), which claims benefit of US Application No. 62/311,224, and is a continuation-in-part of US patent application Ser. No. 14/597,420 (US Pat. No. 9,403,550), which is a continuation-in-part of US patent application Ser. No. 14/261,558 (US Pat. No. 8,955,869), which is a continuation-in-part of US application Ser. No. 12/631,375, which claims the benefit of US Application No. 61/119,920, filed Dec. 4, 2008. US12/633,751 appears to be another patent in this family, likely sharing significant overlap in subject matter. Without the full text, a detailed description is not possible.
  • Potential Anticipated Claim(s): This would likely anticipate claims related to the fundamental concept of a removable seat attachment for a stroller, especially those disclosed in the initial filing from which this application ultimately claims priority (US Application No. 61/119,920, filed Dec. 4, 2008).

• US14/261,558 (Issued as US8955869B2)

  • Publication/Filing Date: Priority claimed from 2014-04-25. Issued as US Pat. No. 8,955,869.
  • Brief Description: This patent is explicitly mentioned as a parent application. It likely deals with a removable seat attachment for a stroller, and given its "continuation-in-part" relationship, it would contain subject matter overlapping with US11731682. The abstract for US11731682 describes "a stroller is provided with the ability to removably couple and decouple a seat from the stroller as needed... including first and second seat attachment housings...Each of the seat attachment housings can include a cavity for receiving a corresponding one of the first and second seat attachment adapters. Each of the seat attachment housings can also include a door cover to prevent access to the respective cavity when not in use." This description suggests that US8955869B2 could potentially cover these core features.
  • Potential Anticipated Claim(s): Claims related to the general system of a stroller with removable seat attachment adapters, seat attachment housings with cavities, and potentially the door covers, as these are described as a core part of the invention in the provided text.

The other listed "Priority claimed from" applications (US17/876,492, US17/877,323, US18/051,053, US18/448,417, US18/534,146, US19/081,266) have priority dates after the filing date of US16/903,292 (June 16, 2020), which is the application number for US11731682. Therefore, these later applications would not be considered prior art under 35 U.S.C. § 102 against US11731682, but rather continuing applications of the same inventive subject matter. US16/903,292 itself is the application number for the patent in question, so it's not prior art.

A complete prior art search would involve examining all "References Cited" in the patent document 11731682 itself, which are not provided in the prompt. This list would offer the most direct prior art considered by the examiner.
