What are the issues with using phrases like “for example,” “such as,” or “or the like” in patent claims?

The MPEP addresses the use of phrases like “for example,” “such as,” or “or the like” in patent claims through specific form paragraphs. These phrases can render claims indefinite under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph.

1. For the phrase “for example,” form paragraph 7.34.08 states:

Regarding claim [1], the phrase “for example” renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d).

2. For the phrase “or the like,” form paragraph 7.34.09 states:

Regarding claim [1], the phrase “or the like” renders the claim(s) indefinite because the claim(s) include(s) elements not actually disclosed (those encompassed by “or the like”), thereby rendering the scope of the claim(s) unascertainable. See MPEP § 2173.05(d).

3. For the phrase “such as,” form paragraph 7.34.10 states:

Regarding claim [1], the phrase “such as” renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d).

These phrases create uncertainty about whether the examples or items following them are part of the claimed invention or merely illustrative, making the scope of the claims unclear.
