Automated Patent Proofreading and Error Detection

It is costly to fix mistakes in issued patents or non-compliant Office Action responses. Some mistakes might significantly limit claim scope or even render patents invalid. Therefore, it is critical to proofread patent applications or the USPTO correspondence prior to filings to spot any potential problems. ClaimMaster provides you with a set of powerful patent tools that will help you proofread patent claims and specifications for mistakes, allowing you to draft higher-quality patent applications without overextending your resources.
