Extensions

To provide a comprehensive overview of US Patent 10,574,721, I need to access the official USPTO records for this specific patent. The provided search results offer general information on patent term adjustments (PTA), patent term extensions (PTE), and different types of continuing applications (continuation, divisional, continuation-in-part), but do not contain the specific details for patent 10,574,721.

The USPTO website's Patent Public Search tool or Patent Center would be the authoritative source for this information. I cannot directly access the live USPTO database or Patent Center through these tools. However, I can infer some information from the patent's metadata provided in the initial prompt and the general rules about patent terms.

Here's a breakdown of what can be determined or inferred, and what would require direct USPTO record access:

Patent Term Adjustment (PTA):

• What it is: PTA extends the term of a patent to compensate for delays caused by the USPTO during the patent examination process. These delays can include the USPTO failing to: issue a first office action within 14 months, respond to an applicant's reply within 4 months, act on an application after a PTAB decision or court decision within 4 months, or issue a patent within 4 months of issue fee payment. Additionally, if the patent doesn't issue within three years of its actual filing date, PTA can be granted. Applicant delays can reduce any awarded PTA.
• For US10574721: The patent was filed on December 8, 2014, and issued on February 25, 2020. This indicates a prosecution period of over five years. It is highly probable that this patent received some PTA due to the length of prosecution exceeding the three-year target for issuance. The specific number of days would be stated on the face of the patent or in the Issue Notification Letter. Without direct access to the patent document or its file wrapper, the exact PTA cannot be determined.

Patent Term Extension (PTE):

• What it is: PTE is available under the Hatch-Waxman Act for patents claiming products (like human and veterinary pharmaceuticals, food additives, color additives, and medical devices) that require regulatory approval from agencies such as the FDA prior to commercial marketing or use. PTE aims to restore a portion of the patent term lost during this regulatory review period and is capped at five years.
• For US10574721: The patent is titled "Systems and methods for an automatic fresh browser instance for accessing internet content." This technology does not appear to fall into the categories of products (drugs, medical devices, food additives, etc.) that typically qualify for PTE. Therefore, it is highly unlikely that US10574721 received any PTE.

Continuation Applications, Divisional Applications, and Related Family Members:

• What they are:
  • Continuation Application (CON): Shares the exact same disclosure as its parent but pursues different claims. No new subject matter can be added.
  • Divisional Application (DIV): Arises when the USPTO issues a restriction requirement, determining that a single application contains two or more independent and distinct inventions. A divisional application claims the benefit of the filing date of the original application.
  • Continuation-in-Part Application (CIP): Incorporates all or part of the parent disclosure and adds new subject matter. Claims supported by the original disclosure get the parent's priority date; claims covering new material get the CIP's filing date.
  • Related Family Members: Include all patent documents that cover the same invention and have at least one common inventor, potentially spanning multiple countries.
• For US10574721:
  • The patent claims benefit to U.S. provisional application Ser. No. 61/912,716, filed on December 6, 2013.
  • The filing date of US10574721 is December 8, 2014, and its application number is US14/563,712.
  • The provided "Other versions" and "Publications" sections on the Google Patents page for US10574721 indicate related publications: US20160164946A1 (published 2016-06-09) and US20170048298A9 (published 2017-02-16). These are likely earlier publications of the same application or continuations.
  • The "Priority Applications" list shows US14/563,712 with the priority date of 2013-12-06.
  • The "Applications Claiming Priority" list includes US201361912716P and US201361192716P (both 2013-12-06) and US14/563,712 (2013-12-06 priority, 2014-12-08 filing). The "P" suffix usually denotes a provisional application.
  • The information states: "Priority to US14/563,712". This patent (US10574721) itself is the granted version of application US14/563,712.
  • Based on the provided data, US10574721B2 is the granted patent from application US14/563,712. US20160164946A1 and US20170048298A9 appear to be pre-grant publications of this same application, possibly with different publication numbers due to reissue or amendment during prosecution. To confirm if there are any other continuation or divisional applications, a detailed search of the USPTO's Patent Center for "Child applications" or "Continuity data" for application US14/563,712 would be required.

Projected Expiration Date:

• General Rule: For utility patents filed on or after June 8, 1995, the patent term generally expires 20 years from the earliest filing date of the application, subject to any PTA or PTE.
• For US10574721: The earliest priority date is December 6, 2013 (from provisional application Ser. No. 61/912,716). The filing date of the non-provisional application US14/563,712 is December 8, 2014. The 20-year term is typically calculated from the earliest non-provisional filing date, or the earliest priority date if it claims benefit from an earlier-filed non-provisional application under 35 U.S.C. §§ 120, 121, or 365(c). Since US10574721 is the granted patent from application US14/563,712, and this application claims priority to a provisional application, the 20-year term typically runs from the filing date of the non-provisional application, December 8, 2014.
  • Therefore, the base expiration date would be December 8, 2034.
  • The provided Google Patents summary lists an "Anticipated expiration" date of 2034-12-08. This aligns with the 20-year term from the filing date of the non-provisional application. Any PTA would extend this date further, but the Google Patents listing does not include a specific PTA amount in this field.

Summary of available information:

• Patent Term Adjustment (PTA): Likely awarded due to the prosecution period of over five years (from December 8, 2014, to February 25, 2020). The exact number of days for PTA is not available in the provided snippets and would require accessing the patent document or its file wrapper.
• Patent Term Extension (PTE): Not applicable, as the patent does not cover products subject to regulatory review (e.g., pharmaceuticals, medical devices).
• Continuation Applications, Divisional Applications, and Related Family Members:
  • The patent claims priority to U.S. provisional application Ser. No. 61/912,716, filed on December 6, 2013.
  • US10574721 is the granted patent from application US14/563,712.
  • Related pre-grant publications are US20160164946A1 and US20170048298A9.
  • No other continuation, continuation-in-part, or divisional applications are explicitly mentioned in the provided data. Further investigation using USPTO's Patent Center or Public Search would be needed to confirm any such applications.
• Projected Expiration Date: The anticipated expiration date is December 8, 2034. This date is calculated as 20 years from the filing date of the non-provisional application (December 8, 2014). This date does not appear to incorporate any potential Patent Term Adjustment, which would extend it further.
