What role do glossaries play in ensuring adequate definition of claim terms?

Glossaries play a crucial role in ensuring adequate definition of claim terms in patent applications. The MPEP 2173.03 specifically mentions the importance of glossaries:

“Glossaries of terms used in the claims are a helpful device for ensuring adequate definition of terms used in claims.”

Glossaries serve several important functions:

  • They provide clear definitions for claim terms
  • They help establish antecedent basis in the specification
  • They assist examiners and the public in understanding the claimed invention
  • They can help prevent rejections based on indefiniteness

By including a glossary in the specification, inventors can proactively define their terms, reducing the likelihood of misinterpretation or disputes over claim scope during examination or potential litigation.
