The Importance of Defining Novel Terms in Patenting Nanotechnology Inventions

Descriptive terminology is essential to providing effective patent protection for nanotechnology inventions, particularly from the perspective of future licensing and litigation activities. One of the key difficulties in patenting nanotech inventions, however, arises from the absence of established terminology. Failure to clearly define one's invention can lead to a number of unfortunate consequences, ranging from an overly narrow patent covering a limited scope of subject matter to a vague or overly broad patent susceptible to invalidation. This article will discuss: 1) recent decisions from the Federal Circuit that reveal how the use of descriptive terminology is essential to patenting nanotech inventions effectively, 2) how those decisions pose special problems for nanotech inventions, and 3) how those problems can be addressed through nanotech inventors acting as their own lexicographers and defining key terms in their patent specifications.
