Patent Attorneys – Orange County, Los Angeles County and Riverside County


At Grant’s Law Firm, our lawyers assist inventors and businesses with obtaining patent protection for the products they or their employees develop. Without a patent obtained by the inventor or owner, others can make, sell, use and import your invention, without permission, and avoid paying any compensation, royalties or license fees.

Patent Rights

Initially vest with the person that conceives of the invention.  For example, if a company hires an independent contractor, patent rights would initially vest with the independent contractor.  If the company hiring the independent contractor wants to exploit the invention, the company must acquire the patent rights from the independent contractor through an assignment.  As such, Companies should negotiate with the independent contractor before hiring the independent contractor with respect to ownership of the intellectual property to prevent any problems down the road.

Types of patents

Our attorneys will assist with any type of patent application. In the United States, Patent protection is only acquired by filing a patent application with the USPTO. The process is complex and can take several years. We will work with you to describe the product as broadly as possible while documenting its novelty. This will maximize licensing possibilities in the future.

Our Southern California patent lawyer can assist you with the process of applying for all types of patents, including:

  • Utility patents. These patents protect the functionality of an invention. They are granted for any new, useful and non-obvious process, machine, manufactured article, composition of matter, and to new and useful improvements of inventions. A utility patent is good for 20 years from the date of filing.
  • Design patents. A design patent protects the overall appearance of an invention, including its ornamental shape and design. It is granted to protect any novel, non-functional design elements and is good for 14 years from the date of the issuance of the patent. In the United States, Ornamental designs of jewelry, furniture, beverage containers and computer icons are examples of objects that are covered by design patents.
  • Provisional patent applications. For those clients with a limited budget who wish to protect their rights quickly, a provisional patent application may be appropriate. Though the provisional patent will expire within one year if it is not upgraded to a utility patent, it will give the inventor a priority date while further resources can be gathered to seek additional infringement protection.
  • Foreign patents. While a patent granted by the U.S. Patent and Trademark Office (USPTO) protects a patent in all 50 States and U.S. territories and possessions, the Patent Cooperation Treaty (PCT) allows a patent applicant to achieve protection of an invention in other countries throughout the world who are signatories of the PCT.

Follow-up by experienced patent attorney

After your patent application has been filed, the USPTO usually issues at least one Office Action. It is necessary at that point to present arguments to the patent examiner why the invention is patentable and distinct based upon the differences between the invention and the prior art cited by the examiner. We assist clients with this process.


For entrepreneurs not interested in producing their inventions, our licensing attorneys can help license your patents to manufacturers. We can help you develop a license agreement that will protect your invention and compensate you for your contribution. Conversely, for businesses interested in using the patented product of an inventor, Grant’s Law Firm, can help negotiate a License so the business can lawfully make, use, sell or import the product.

Take action before your ideas and rights slip away. Contact our Patent Lawyers in Irvine, Glendale, or Riverside office to discuss any issue related to patents.
