Patent Warning Letters, Lawsuits and Infringement in Germany

Specialized legal defense against patent attacks and strategic enforcement of your intellectual property rights — before German patent courts and the Unified Patent Court (UPC).

Received a Patent Cease-and-Desist Letter?

Many medium-sized companies are suddenly confronted with patent infringement allegations — often without prior warning and with potentially devastating financial demands. Typical situations include:

• You have received a warning letter alleging patent infringement and are being asked to sign a cease-and-desist undertaking with high contractual penalties
• A competitor has obtained a preliminary injunction without warning — your production or distribution is at risk
• You have been sued before a patent litigation division or the UPC and must defend yourself
• Warning letters demand five-figure legal fees plus five- to six-figure lump-sum license/settlement payments
• You want to launch a new product and need an assessment of possible patent infringement risks

Defense Against Patent Attacks — My Strategy for You

• Defense Against Patent Infringement Allegations: Thorough examination of the allegations, analysis of the technical and legal situation, and development of a tailored defense strategy
• Attacking Weak Patents: Many patents do not withstand legal and technical scrutiny. Invalidity proceedings before the Federal Patent Court or the UPC create freedom to operate for your business
• Nationwide Representation — Including the UPC: Representation throughout Germany before all patent litigation divisions, Higher Regional Courts, the Federal Patent Court, and the Unified Patent Court
• Cost-Effective Approach: Cost-efficient strategies with transparent budgeting that minimize litigation risk and favor out-of-court solutions where economically sensible
