Patenting an Invention: Expert Guidance from Filing to Enforcement

An invention qualifies as patent-eligible subject matter under 35 U.S.C. § 101 when it falls within one of the four statutory categories, which are a process, a machine, a manufacture, or a composition of matter, and is not directed to a judicially recognized exception such as an abstract idea, a law of nature, or a natural phenomenon. Patentable-invention and patent-counseling counsel can evaluate whether the claimed invention satisfies the subject matter eligibility requirements under 35 U.S.C. § 101, assess the specific legal basis for any patent eligibility challenge the USPTO examiner is likely to raise, and advise on the claim drafting strategy that most effectively characterizes the invention in terms that satisfy the applicable eligibility requirements while preserving the broadest possible scope of protection.

An invention satisfies the novelty requirement under 35 U.S.C. § 102 when it is not anticipated by a single prior art reference that discloses every limitation of the claimed invention, and satisfies the non-obviousness requirement under § 103 when the differences between the claimed invention and the prior art would not have been obvious to a person of ordinary skill in the art. Technology-patent-law and patent-counseling-prosecution counsel can advise on the prior art search strategy required to assess the novelty and non-obviousness of the invention before filing, assess whether the differences between the claimed invention and the most relevant prior art are sufficient to support a finding of non-obviousness under the Graham v. John Deere framework, and develop the experimental evidence and secondary consideration arguments required to rebut a prima facie case of obviousness.

The independent claims define the outer boundaries of the patent owner's legal monopoly, and every word in an independent claim is a limitation that a potential infringer can use as a basis for arguing non-infringement, which means that claims drafted too narrowly fail to cover competing products that achieve the same result through minor variations, while claims drafted too broadly will be rejected or invalidated. Patent-prosecution and intellectual-property-registration counsel can advise on the claim drafting strategy for a patent application, assess whether the proposed independent and dependent claims define the invention with sufficient precision to provide meaningful legal protection against competing products and processes, and develop the claim hierarchy that most effectively captures the full scope of the invention while maintaining enforceability against the range of potential infringers.

The specification must provide a written description that demonstrates the applicant's actual possession of the full scope of the claimed invention at the time of filing, and must enable a person of ordinary skill in the art to make and use the invention without undue experimentation, and the applicant who files a specification that does not satisfy both requirements risks having the patent invalidated. Startup-patent-strategy and intellectual-property counsel can advise on the specification drafting strategy for a patent application, assess whether the specification provides adequate written description and enablement support for all of the claims in the application, and develop the specification content required to prevent the examiner from raising written description or enablement rejections that could narrow the scope of the patent.

A patent office action is a formal written communication from the USPTO examiner that sets out the legal and factual basis for the examiner's rejection of some or all of the claims, and the applicant has three months from the mailing date to respond, and the response strategy selected at this stage significantly affects both the scope of the patent and its ultimate validity. Patent-counseling and software-patent-law counsel can advise on the legal arguments and claim amendments available to overcome a rejection issued in a patent office action, assess whether the examiner's rejection is legally and technically correct and identify the weaknesses in the examiner's reasoning, and develop the response strategy that most effectively advances prosecution toward allowance without unnecessarily limiting the scope of the patent.

A PCT application filed under the Patent Cooperation Treaty allows the applicant to simultaneously preserve patent rights in over 150 member countries with a single filing, deferring national phase entry for up to thirty months from the priority date, and the applicant can use this window to conduct market assessments before committing to the expense of national phase prosecution. Patent-prosecution and data-rights-patents counsel can advise on the international patent filing strategy for an invention with commercial potential in multiple jurisdictions, assess whether the applicant's commercial objectives are best served by a direct national phase filing or by a PCT application that preserves the priority date across all designated countries, and develop the international prosecution strategy that most cost-effectively builds the global patent portfolio.

Patent infringement occurs when a competitor makes, uses, sells, offers for sale, or imports a product or process within the scope of one or more valid patent claims without authorization, and the patent owner who discovers infringement can seek injunctive relief, actual damages, and enhanced damages of up to three times the actual damages for willful infringement under 35 U.S.C. § 284. Patent-infringement-litigation and injunctive-relief counsel can advise the patent owner on the legal requirements for asserting a patent infringement claim against a competitor's product or process, assess whether the accused product or process falls within the literal scope of the patent claims or under the doctrine of equivalents, and develop the litigation strategy that most effectively enforces the patent owner's rights and removes the infringing product from the market.

Inter partes review is an adversarial proceeding before the Patent Trial and Appeal Board in which a petitioner challenges the validity of issued patent claims on the basis of patents or printed publications, and the patent owner who fails to prepare for an IPR petition risks having the most valuable claims cancelled. Patent-infringement-litigation and preliminary-injunction counsel can advise the patent owner on the legal arguments and evidence required to defend against an inter partes review or post-grant review petition filed by a competitor, assess the validity of the patent claims under review and identify the prior art and claim construction arguments that most effectively establish that the challenged claims are patentable, and develop the patent owner's response strategy before the Patent Trial and Appeal Board.
