Leech Tishman’s Intellectual Property team regularly conducts patent validity studies for clients, patent infringement analyses, and patent clearance/freedom to operate studies.
Clients hire our highly-skilled attorneys to conduct patent validity studies of issued patents in order to determine if the patent would likely be cancelled by the U.S. Patent and Trademark Office or if the claims against the patent would be found valid by a court.
Our attorneys regularly write patent validity opinions with the intention that they be used in court as evidence of non-willful infringement.
Clients often hire us to determine if a product or service want to bring to market might infringe on a patent, or to analyze if other businesses might be selling a product or service that would infringe on their patent. In these cases, our lawyers conduct a patent infringement study focused on a single blocking patent.
Freedom to Operate Opinion
Many businesses conduct “freedom to operate” studies (also known as patent clearance studies) to ensure that their proposed product will not infringe on valid, enforceable patents in the country where they are planning to go to market. These studies look into existing licenses, ownership, patent expiration, validity, infringement, and covenants not to sue.
