What does “prolix” mean in patent claims?
In patent law, “prolix” refers to claims that are excessively wordy, lengthy, or contain unnecessary details that make it difficult to determine the scope of the claimed invention. According to MPEP 2173.05(m), examiners may reject claims as prolix “when they contain such long recitations or unimportant details that the scope of the claimed invention is rendered indefinite thereby.”
Prolix claims can make it challenging for patent examiners and others to understand the boundaries of the invention, potentially leading to indefiniteness rejections under 35 U.S.C. 112(b).
