Patent Enforcement Analysis: Safeguarding Your Innovation with Strategic Enforcement
A patent earns its value when its owner can show that someone is using the invention without permission. Before sending a notice, offering a licence or filing suit, the owner needs answers to three questions. Who is infringing? How strong is the evidence? How strong is the patent itself? Patent Enforcement Analysis answers them, giving you a clear basis for choosing between a cease-and-desist notice, a licensing negotiation and litigation.
What We Offer
Claim scope analysis to define exactly what each patent covers
Identification of potential infringers through market, product and competitor research
Evidence gathering from product literature, technical documentation, teardown reports and reverse engineering
Claim charts comparing patent claims with each suspected infringing product
Validity and enforceability review of the patent to be asserted
Recommendations on the best enforcement route, jurisdiction and timing

Our Approach
Define the claims. We analyse the patent's claims and prosecution history to establish the scope that can realistically be enforced.
Find the products. We research the market, competitor launches and industry reports to identify products and processes that may fall within the claims.
Build the evidence. We collect technical and commercial evidence and set it out in claim charts against each target.
Test the patent. We assess the patent's own validity, so you are not surprised by an invalidity counter-attack.
Recommend the route. We advise whether to pursue a notice, a licence or litigation, and in which jurisdiction.
