similar patent applications filed within 6 months of each other), a patent
court uses laboratory records documenting the first evidence of the inven-
tion in order to reach a decision. In Europe and the majority of the World
Trade Organization (WTO), priority is determined solely by who was the
“first to file”; in other words, the “priority date” is everything.
The timing of invention (often called “reduction to practice”) can be
established in several ways in the United States. One is by the records
established in bound laboratory notebooks that have been routinely
signed, witnessed, and dated on a regular basis. Another is by a Record
of Invention filed by the investigator/inventor within his or her own insti-
tution. This is a formal document prepared in conjunction with the
Technology Transfer Office stating the idea that will be patented, the inven-
tors of the idea, and the date. It is best to combine this with the signed and
dated copies of notebook pages outlining the data contributing to the inven-
tion and the original statement of the invention, if this exists.
A safer way to protect the date of invention is to establish a “priority
date,” or filing date, by filing a Provisional Patent Application. This is a
document that can be filed in the U.S. Patent and Trademark Office
(USPTO) to establish the date of invention. It generally includes all of
the data to be filed, a statement of the invention, and any background
information (e.g., publications, patents) that may be required. There are no
formal documentation requirements for a Provisional Patent Application
since it is not actually examined by the patent office. However, it must
adequately disclose the broadest aspects of the invention.
PATENTABILITY
What can be patented? The right to patent an idea or invention is estab-
lished in the U.S. Constitution. The USPTO determines the merits of a
patent application based on three criteria: novelty, utility, and nonobvious-
ness. A novel idea must not have been known or used by anyone in the
public domain (worldwide) prior to the patent application. Moreover, you
or anyone else cannot have used the idea in a commercial manner for more
than 1 year prior to the filing date. If your company has made a novel dis-
covery and you have offered it for sale or to customers in the form of a
service, you jeopardize your opportunity to protect the product with a
patent. Utility must be demonstrated to the patent office in the form of an
example or application. The nonobviousness of the invention will be deter-
mined by “those skilled in the art”; in other words, a hypothetical colleague
with training similar to your own should not be able to reach the identical
conclusion without your help. To find out about existing inventions or
patents similar to your own in the patent literature, you can search public
