To maximize return on R&D investment and maintain competitive advantage, companies may want to keep evaluating if someone else is making, using, or selling product using their protected invention. Infringement analysis is conducted in order to determine whether a product or a process infringes upon an existing patent claim. We scope coverage of a given claim after going through the detail description and analyzing prosecution history, and then identify potential infringing product/services. We analyze product features from literal infringement and as well as from infringement under Doctrine of Equivalence standpoint. Our report present list of potential infringing products, and high level product features to claim elements mapping. We can also provide detailed claim charts illustrating one to one mapping of claim elements to product features. For a given patent portfolio, we keep evaluating potential licensing opportunity for our client.
