How does timely disclosure of information affect patent validity?

Timely disclosure of information can significantly affect patent validity. The MPEP states: The presumption of validity is generally strong when prior art was before and considered by the Office and weak when it was not. This means that when relevant information is disclosed promptly and considered by the USPTO during examination, the resulting patent is more likely to be considered valid if challenged later.

Timely disclosure allows the examiner to thoroughly evaluate the patentability of the invention in light of all relevant information. This comprehensive examination strengthens the patent’s presumption of validity, making it more resilient to future challenges based on prior art or other material information.
