The U.S. Patent and Trademark Office issues a reexamination certificate after reviewing a patent to determine the validity of its claims. This certificate confirms whether the patent is still in effect or if certain claims have been removed due to being found invalid. Additionally, the certificate may include new claims that have been deemed valid.
The U.S. Patent and Trademark Office issues a reexamination certificate after a reexamination proceeding. This certificate confirms that a patent has undergone reexamination and that the claims found to be patentable have been upheld. It also confirms the cancellation of any claims deemed unpatentable. Additionally, the certificate may include any newly added or amended claims that have been determined to be patentable. For instance, if a patent holder requests a reexamination and the Patent Office determines that certain claims are not patentable, those claims will be canceled and the reexamination certificate will reflect this change. Conversely, if the Patent Office determines that new claims are patentable, they will be added to the patent and the reexamination certificate will reflect this change.
A reexamination certificate is a document issued by the United States Patent and Trademark Office (USPTO) that confirms the outcome of a reexamination proceeding for a patent. It indicates whether the patent claims have been amended, canceled, or confirmed.

A reexamination certificate can be used as evidence to challenge the validity of a patent’s claims. However, it does not automatically invalidate a patent. The ultimate determination of a patent’s validity lies with the courts or the USPTO’s PTAB.
