A submarine patent is a patent whose issuance and publication are intentionally delayed by the applicant for an artificially long pendency, which can be several years, or a decade. Analogous to a submarine, submarine patents could remain "under water" for long periods until they "emerge", surprising the relevant market and potential infringers.
