FAQs Patent Questions
Question:How do I search for a particular type of patent, e.g., a design patent?
Answer: To search for a particular type of patent, go to any one of the three search pages (Quick, Advanced, Number) and, in the appropriate patent number field (Patent Number, PN/, Query), enter the patent number including the appropriate prefix: 'D' for design patents, 'PP' for plant patents, 'R' for reissue patents, 'T' for defensive publications, 'H' for SIRs, 'X' for X patents, or 'AI' for Additional Improvements
Question:Design patents are granted to inventors who discover a new design for an article of manufacture.
Answer:
File a Design Patent Application - Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.
Question:An inventor faces possible loss of benefits during his two-year retention period.
Answer:
The two-year retention period is not a “grace period” during which the inventor can wait to file his or her patent application without possible loss of benefits. It must be recognized that, in establishing priority of invention, an affidavit or testimony referring to a Disclosure Document must usually also establish diligence in completing the invention or in filing the patent application after the filing of the Disclosure Document.
