What is the significance of the two-year time limit for broadening reissue applications?
The two-year time limit for filing broadening reissue applications is a critical deadline in patent law. MPEP 1410 states: “A broadening reissue application must be filed within two years from the grant of the original patent.” This time limit is mandated by 35 U.S.C. 251.
The significance of this time limit includes:
- It provides a definite period for patent owners to seek broader protection.
- It balances the interests of patent owners and the public by limiting the time during which the scope of a patent can be expanded.
- After two years, only narrowing reissue applications can be filed.
- The deadline is strictly enforced and cannot be extended.
It’s important to note that while the application must be filed within two years, the actual broadening of claims can occur later during prosecution. Patent owners should carefully consider their patent strategy within this two-year window to maximize protection for their inventions.
