4. Common Pitfalls Regarding Patents

i. The One Year "On Sale" Bar

In the United States, a patent application must be filed within 1 year of the first offer for sale or the first public disclosure of the invention. The offer for sale can occur even before the product has been built (this is a common practice in custom software). Thus, it is important to document any sales activity and to ensure that patent applications are filed within the 1 year time frame.

ii. Proper Inventorship

In the United States, patent applications are filed in the name of the inventors, not their employers. It is therefore important to properly name those who were involved with the invention. If it is determined that the inventorship has been deliberately misrepresented, the patent can be invalidated. Therefore, it is important to determine who actually was involved with the invention set forth in the claims of the patent application. Just because you own the company does not mean you should be listed on the patent.

iii. Absolute Novelty

Unlike the United States, most countries require "absolute novelty." In other words, a patent cannot be filed after there has been public disclosure of the invention. Thus, if patent rights are desired in foreign countries it is important to file the patent application before any public disclosure.

iv. Medical Procedures

In many countries medical procedures or any method for treating the human body are not patentable subject matter. In the United States, a patent may be obtained for a medical procedure, however, doctors are not liable for infringement when performing the medical procedure. This does not mean, however, that a patent on a medical procedure is completely without value. Often a medical products company may be a contributory infringer if they provide materials that facilitate infringement of the patent's claims.
