Can an amendment be denied entry in a patent application?

Yes, an amendment can be denied entry in certain circumstances. The MPEP 714.21 references this possibility:

See 37 CFR 1.3 and MPEP § 714.25 for an example of a paper which may be denied entry.

This indicates that there are specific rules and guidelines governing when an amendment may be denied entry. For example, MPEP 714.25 discusses the denial of entry for papers containing discourteous language. It’s important for patent applicants and attorneys to be aware of these rules to ensure their amendments are properly considered.
