What type of information must be listed in an IDS for items not in English?

When submitting an Information Disclosure Statement (IDS) to the United States Patent and Trademark Office (USPTO), any references that are not in English must be accompanied by a list that includes concise explanations of their relevance to the claimed invention. This requirement ensures that the examiner understands the significance and relevance of the non-English references in the context of the application being examined.

Providing concise explanations allows the examiner to evaluate the potential impact of these references on the patentability of the claimed invention. The purpose of this requirement is to facilitate the examination process, making it easier for the examiner to assess whether the references are indeed relevant prior art that must be considered.

This approach contrasts with the requirements for English references, which do not necessitate such an explanation. Thus, while the correct answer emphasizes the need for relevance explanations for non-English items, it underscores the importance of clarity and thoroughness in patent prosecution.
