Our Specialization


A patent is a granted property right to the inventor, issued by the US Patent and Trademark Office (USPTO).  Generally, the duration of a new patent is 20 years from the date on which the patent application was filed. A patent is not only a symbol of innovation, it is the spark that ignites and drives the engine of our modern economy and it provides the framework for business success. Our patent professionals offer a full range of services in patent prosecution and litigation in the technical fields of biotechnology, software, electronics, chemistry, pharmaceuticals, nanotechnology, semiconductor and mechanical/medical devices.

Copyright is a form of legal protection for written works including computer software, music and recordings, dramatic works, choreographic works, photographs, paintings, graphics, sculptures, audio video works, and architectural works. Copyright notice is not required because copyright is secured automatically when the work is created. However, there are advantages to use a copyright notice since it advises potential infringers that the work is protected by copyright, and it can be used to show that the infringement was not an accident. A copyright notice includes (1) the symbol ©, the word “Copyright”, (2) the publication year, and (3) the owner’s name. Registration requires filing an application and a copy of the work with the Copyright Office.


Services provided by our copyright professionals include:

  • Copyright registration
  • Copyright litigation
