IP Due Diligence: what the service is for
Forensic audit of target IP portfolios for corporate acquisitions, venture funding rounds, and joint ventures. We verify title chains, assignment records, security interests, open-source contamination, and patent enforceability. The practical purpose of this service is to review ownership, status, encumbrances, portfolio records, and technical risk in a transaction. Patent research and technical analysis should be scoped around the claim, technology, dates, and jurisdictions that matter to the matter.
When this service is useful
The service can be used before a filing, during prosecution, as part of a product or brand decision, during a transaction, or when a dispute requires a well-organized technical record. The right depth depends on the question being asked. A focused assignment is generally more useful than a broad request that does not identify the decision, jurisdiction, date range, or evidence that matters.
Scope and review approach
The work starts by defining the subject matter and the boundaries of the assignment. For research matters, this normally includes relevant dates, jurisdictions, entities, technical terminology, classification concepts, and known references. For operational matters, it includes the matter record, source correspondence, procedural event, deadline rule, and required output. Findings are separated from assumptions so that the final material can be reviewed by counsel or the responsible business team.

Where it is commonly used
Tech Mergers & Acquisitions — Acquiring Corporations & Legal Counsel. Uncover hidden IP title defects and patent litigation liabilities before closing.
Useful starting material may include the invention disclosure, claims, product specifications, prosecution history, trademark specimen, portfolio export, official correspondence, target jurisdictions, priority dates, known references, or a specific list of questions. If some information is missing, the scope should identify that limitation instead of filling gaps with assumptions.
Important review point
Research and operational support are decision-support services. They do not replace legal advice, a patentability or validity opinion, an infringement opinion, a trademark clearance opinion, or an official determination by a government office. Patent and trademark rights can depend on claim construction, evidence, procedural history, local law, and facts that may change over time. The final work should therefore be reviewed by the attorney or other qualified professional responsible for the matter.
Frequently asked questions
What are the most common IP red flags in M&A?
Missing inventor assignment forms, expired maintenance fees, undisclosed competitor infringement notices, and restrictive open source (GPL) code.
