A patent owner has the legal right to prevent others from making, using, selling, importing, or exporting products or goods that encompass the idea described in the patent. At Wang IP Law Group, P.C., our attorneys are not only trained in technical and industry knowledge, but also experienced in all aspects of patent litigation, prosecution, enforcement, negotiation, and appeals.

Patent Prosecution 

We have extensive experience in preparing and prosecuting patent applications with the USPTO to stop patent infringement.  Our firm prides itself on preparing client-tailored patent applications to help our clients achieve specific goals for their inventions and creations. We carefully listen to our clients needs and goals, identify potential issues, and develop appropriate and cost-effective patent portfolios to obtain these results for longterm solutions and protection.

At Wang IP Law, we realize how costly and inefficient patent litigation can be and keep this in mind when we prepare every patent.  However, if patent enforcement is necessary, our attorneys are ready with creative and aggressive litigation tactics to help you protect your patent rights, beginning with a strong grasp of potential prior art and following through to motions for summary judgment, and trial and appeal. Our services include rendering patent validity and infringement opinions; conducting appeals interferences, oppositions, reexaminations and reissue proceedings; and securing protection in foreign countries as well.

 Patent Defense

Our attorneys are equally well-versed in defending against patent infringement charges. We understand how expensive patent litigation is, particularly when our clients find themselves on the defense.  Our firm possesses the skills and experience to identify, evaluate and establish defenses for our clients to maximize results while minimizing costs.

Our patent services include:

  • Reexamination to challenge the validity of a patent;
  •  “Freedom to Operate” research and analysis
  • Evaluation of clients’ investment in product development identification;
  •  Assessment of risks posed by the competition; and
  • Creative defense planning to protect our clients against identified risks.
