Industry Awards

Patent attorneys protect innovations worth millions, often billions, in commercial value. A single drafting error can limit patent scope, while a missed deadline can destroy priority rights entirely. Professional Indemnity insurance gives your practice protection when patent advice, drafting, prosecution or deadline management is challenged.

Practice Structure

Individual registration and incorporated-firm obligations are different. Incorporated patent-attorney firms must consider specific PI requirements; individual attorneys and sole practitioners usually need cover because clients, panels and professional risk make it essential.

Our Approach

We work with IP practices of all sizes, from sole practitioners to major firms. Our brokers understand patent practice and source coverage from insurers experienced in professional IP services.

QUESTIONS

Patent Attorney PI Insurance FAQs

PI insurance for patent attorneys covers claims arising from professional negligence in patent practice. This includes errors in application drafting, claim construction, prior art searches, freedom-to-operate opinions, and deadline management that cause financial loss to clients. Coverage extends to legal defence costs and compensation for negligent patent services.
Patent attorneys should carry Professional Indemnity insurance, but the obligation depends on how the practice is structured. Individual patent attorney registration is managed through the Trans-Tasman IP Attorneys Board. Incorporated patent-attorney firms have separate requirements to maintain adequate and appropriate PI insurance, while sole practitioners and individual attorneys still usually need cover for client contracts, panel requirements and professional protection.
Key risks include drafting errors that limit patent protection scope, missed filing deadlines causing loss of priority dates or patent rights, inadequate prior art searches missing relevant references, claim construction errors affecting enforceability, and failure to advise on maintenance requirements leading to patent lapse.
Yes. Incorporated patent-attorney firms have different PI obligations to individual registered attorneys. We check your structure, services and client contracts before recommending limits, retroactive cover and policy wording.
Coverage requirements depend on your practice size, client base and the value of the IP portfolios you manage. Many practices carry higher limits where they advise on priority dates, PCT filings, freedom-to-operate opinions or high-value patent portfolios. We assess your practice profile and recommend appropriate cover.
