The non-infringement defence is based on the idea that even if your patent is legitimate, the allegedly infringing product or method does not correspond to the claimed innovation. Claim establishes the extent of the innovation or the exclusivity of the inventor’s right according to contemporary patent infringement rules. The preamble of a patent claim and a list of restrictions that describe the invention, are typically the two main components for infringing the patent.
As a result, for a product or method to be considered an infringement, it must meet all of the claimed invention’s features, either exactly or in accordance with the theory of equivalents, in order to be included within the patent claim’s purview.
As a patent is a legal document, you can consult to a patent attorney or an IP specialist to ascertain the claim’s scope. You can evade the claim if your product is still in its development to avoid infringement. Patent infringement can be prevented if it is judged that the product is not within the invention’s purview.
