A legal firm assessing patents is responsible for conducting thorough searches of existing patents, preparing and filing patent applications, communicating with the USPTO, and providing legal advice on patent strategy, enforcement, and defense1. They also assist in patent litigation, licensing, and transactions, as well as manage intellectual property portfolios for clients.
Lawyers typically search for prior art by consulting with third-party search providers who conduct boolean keyword searches on databases such as Google Patents and other legal research tools. They assess the claims about the prior art by reviewing each document multiple times to find and organize the necessary wording, which can take 20 to 40 billable hours for each patent and case.
Lawyers use various databases and search platforms for boolean keyword searches, including Google Patents, Westlaw, LexisNexis, Bloomberg Law, and Casetext. These tools allow lawyers to conduct precise searches by combining keywords with boolean operators (AND, OR, NOT) to retrieve relevant results for their legal research.
