How does the USPTO evaluate the credibility of affidavits or declarations?
The United States Patent and Trademark Office (USPTO) carefully evaluates the credibility of affidavits or declarations submitted as evidence in patent applications. The MPEP 716.01(c) provides guidance on this matter:
In assessing the probative value of an expert opinion, the examiner must consider the nature of the matter sought to be established, the strength of any opposing evidence, the interest of the expert in the outcome of the case, and the presence or absence of factual support for the expert’s opinion.
When evaluating the credibility of affidavits or declarations, examiners consider several factors:
- Relevance: The evidence must be directly related to the patentability issues at hand.
- Expertise: The qualifications and experience of the person providing the affidavit or declaration.
- Factual support: The presence of objective data or observations backing up any opinions or conclusions.
- Consistency: How well the evidence aligns with other information in the application and known facts.
- Potential bias: Any interest the declarant may have in the outcome of the application.
Examiners are instructed to give appropriate weight to credible evidence while scrutinizing any statements that appear unsupported or potentially biased. The overall goal is to ensure that patentability decisions are based on reliable and relevant information.
