Understanding the Patent Process from Soup to Nuts


A patent grants the inventor the right to exclude others from making, using, selling or offering to sell the invention throughout the United States, or from importing the invention into the United States for a limited period of time. To obtain a patent, the inventor submits an application with the United States Patent and Trademark Office (known as the “USPTO”). The application must be submitted within one year of public use or publication of the invention. There are four categories of patents available:

  • Utility patents, which are the most common, are issued to protect new, useful, non-obvious and adequately specified articles of manufacture, machine processes, compositions of matter, or any improvements thereto, for a period of twenty years from the filing date of the application.
  • Design patents are issued to protect new, original, ornamental, and non-obvious designs for articles of manufacture for a period of fourteen years from the date the patent is granted.
  • Plant patents, the least used, are issue to protect certain new varieties of plants that have been asexually reproduced for a term of twenty years from the filing date of the application.
  • Business model patents, or novel methods of business, were deemed patentable in the late 1990’s by the United States Circuit Court for the Federal Circuit. Ruling in the landmark case of State Street Bank v. Signature Financial Group, Inc., the court found that Signature’s patent for its “hub and spoke” mutual fund management process was valid.

With the increased popularity of the Internet, many ways of doing business in cyberspace are being viewed as novel and patentable. Perhaps the best known Internet-related business model patents recently issued are for Priceline.com's reverse auction method and Amazon.com's “one-click” purchase feature. Both of these patent owners are aggressively trying to enforce their patents – Priceline.com by challenging a similar service offered by Microsoft and Amazon.com by challenging Barnesandnoble.com's Express Lane online purchasing feature. With the onslaught of these business model patents, if your business is dependent on a proprietary business method or system, as is the case with so many businesses, then the business should consider the costs and benefits of patent protection. However, the window may soon be closing on the number of business model patents that the USPTO is willing to grant given the current backlog of filings as well as the policy concerns which have been expressed if too many of these are granted.

Compile and Maintain Careful Records

If your company decides to pursue a patent, before retaining a patent attorney, make sure you compile and maintain careful records relating to the research and testing of the invention. The records should contain key dates, including the date the invention was conceived and the date it was reduced to practice (meaning, the date the invention is well beyond the conceptual stage, and has either actually been developed and tested, or is so clearly described in the application that a third party skilled in the particular art could understand and actually develop the technology).

The records should also demonstrate your diligence in developing and testing the invention. Make sure the records contain the corroboration of independent witnesses who are capable of understanding the nature and scope of the invention and who will verify the dates mentioned above.

Conduct a Patent Search

The next step is to conduct a search at the USPTO Public Search Room, located in northern Virginia, just outside of Washington, DC. An attorney experienced in this area usually conducts the search. The search will reveal those patents in your field that have already been issued and how these patents may affect your application. The ramifications of any previously issued patents should be thoroughly discussed with your advisor and may factor into your decision to apply for a patent.

The Application Process

The prosecution of a patent application is a complex process. First, the actual application must be compiled. The application consists of the following distinct parts:

  • A clear and concise declaration that you are the original and sole inventor of the subject matter of the application.
  • Drawings of the invention (where applicable and necessary).
  • One or more “claims of exclusivity” (these claims define the actual boundaries of the exclusive rights you hope to be granted – if drafted too narrowly, imitators and competitors may be able to develop similar technologies and processes without fear of infringement; if drafted too broadly, you run the risk of rejection by the USPTO examiner or subsequent challenge to the patent’s validity by a competitor).
  • The appropriate filing fees.

Once filed, a patent examiner at the USPTO will review the application to determine the patentability of the invention. As part of this review, the examiner will determine whether or not you have met the following statutory requirements:

  • The invention consists of patentable subject matter (i.e., a process, machine, composition of matter or article of manufacture, or a new and useful improvements to one of these).
  • You are the original inventor or discoverer of the subject matter described in the patent application.
  • The subject matter is new or novel (i.e., it is not already known to or used by others, has not been previously described in a printed publication, and is not merely a new use of an existing product).
  • The subject matter is useful and not merely of scientific or philosophical interest.
  • The subject matter is non-obvious to others in that particular trade or industry, as determined in the broad discretion of the USPTO examiner (i.e., the differences between the subject matter of the application and the current body of knowledge of those skilled in that area are more than marginal).

Protecting Your Patent

In order to preserve your rights, and continue to protect your interests, it is imperative that you institute an aggressive patent protection program once you obtain your patent. While the costs of such a program may be high, especially if you undertake any patent litigation, the rewards will be worthwhile. Should you successfully pursue an infringer, you may be entitled to an award of damages (which may be tripled by the court in extraordinary cases), as well as equitable relief, such as an injunction or accounting for profits.

Your patent protection program should include:

  • The use of proper notices of the existence of the patent on all labeling and marketing of the invention.
  • Ongoing monitoring of new industry developments.
  • Policing (and limiting) the activities of employees, licensees, and others who come into contact with the subject matter of the patent.
  • Exploiting and saturating the market created by the patented product.
  • Pursuing known or suspected infringers of the patent.
