Infringement Analysis Â
The United States Code states:Â Â
Except as otherwise provided in this title, whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent, therefore, infringes the patent.Â
 In this context, there are various ways that infringement can happen. The term “literal infringement” refers to the proposed product really violating the written claim. Â
The “doctrine of equivalents,” a judicially developed doctrine, attaches infringement liability even in the absence of literal infringement, even when the infringing device or process does not fall within the literal scope of a patent claim, but is nonetheless equivalent to the claimed invention. Â
Infringement may also be “direct,” “contributory,” or “induced.” Making, using, proposing to sell, selling, or importing any patented invention into the United States without authorization throughout the patent’s term constitutes a direct infringement of the patent. Â
When a device is claimed in a patent and a third party provides a product that can only be legitimately utilized to create the claimed device, this is an example of indirect infringement. Infringement that is “contributory” or “induced” is referred to as indirect infringement in the US.
Invalidity AnalysisÂ
An invention must be patentable, novel, and non–obvious in order for a claim to be considered valid, and the specification must adhere to the standards set forth in 35 U.S.C. 112 (including definiteness, written descriptions, enablement, and best mode).Â
