Extensions

US Patent 12195773, titled "PH20 polypeptide variants, formulations and uses thereof," has a filing date of May 9, 2024, and was granted on January 14, 2025.

Patent Term Adjustments (PTA) and Extensions (PTE)

As of the current date (April 26, 2026), specific details regarding Patent Term Adjustments (PTA) and Patent Term Extensions (PTE) for US12195773 are not explicitly provided within the patent document itself or the available Google Patents information.

• Patent Term Adjustment (PTA): PTA is granted to compensate for administrative delays by the USPTO during the prosecution of a patent application. This can include delays such as failing to issue a first office action within 14 months, responding to an applicant's reply within four months, or issuing the patent within four months of the issue fee payment, or within 36 months from the filing date. Any PTA can be reduced if the applicant causes delays. Since the patent was filed on May 9, 2024, and granted on January 14, 2025, it had a relatively short prosecution period of approximately 8 months. This short timeframe suggests that significant USPTO delays warranting a large PTA are unlikely. However, a definitive PTA calculation would require examining the prosecution history of the specific application.
• Patent Term Extension (PTE): PTE is awarded to compensate for delays incurred in obtaining regulatory approval on a patented product, such as a pharmaceutical product. Given that the patent concerns "PH20 polypeptide variants, formulations and uses thereof," and Halozyme Inc. is a pharmaceutical company, it is possible that PTE may be sought if a product covered by the patent requires regulatory approval. However, the grant of PTE would occur much later, typically after regulatory approval is obtained, and is not something that would be determined at this stage.

Continuation and Divisional Applications

The provided patent information explicitly states that US application Ser. No. 18/659,215, which matured into US12195773B2, is a continuation of prior applications.

• Continuation Applications:
  • U.S. application Ser. No. 17/327,568.
  • U.S. application Ser. No. 16/824,572, which issued as U.S. Pat. No. 11,041,149 on June 22, 2021.
  • U.S. application Ser. No. 15/226,489, which issued as U.S. Pat. No. 10,865,400 on December 15, 2020.
  • U.S. application Ser. No. 13/694,731, which issued as U.S. Pat. No. 9,447,401 on September 20, 2016.
    Continuation applications generally pursue additional claims or improvements related to the original invention and share the same filing date and are subject to the same prior art references as their parent applications.
• Divisional Applications: The immediate patent, US12195773B2, is a continuation and not a divisional application. However, U.S. application Ser. No. 15/226,489 (U.S. Pat. No. 10,865,400) is noted as a divisional of U.S. application Ser. No. 13/694,731 (U.S. Pat. No. 9,447,401). Divisional applications are filed to pursue distinct inventions that were subject to a restriction requirement in the parent application.

Related Family Members

Projected Expiration Date

The "Anticipated expiration" date listed for US12195773B2 is December 28, 2032. This date is typically 20 years from the earliest non-provisional filing date to which the patent claims priority, plus any applicable Patent Term Adjustment (PTA). The original priority date is December 30, 2011 (from U.S. Provisional Application No. 61/631,313), and the earliest non-provisional filing in the chain appears to be U.S. application Ser. No. 13/694,731, filed on December 28, 2012. Twenty years from December 28, 2012, would be December 28, 2032. The listed anticipated expiration date of December 28, 2032, suggests that any PTA awarded did not extend the term beyond this date, or that this date already accounts for any PTA.
