What this record means
The record shows that WORDNET, owned by the Trustees of Princeton University, The, was registered on the Principal Register for computer programs that act as an inter‑relational dictionary or lexicon of the English language for use in information retrieval, machine translation, vocabulary instruction and text editing, and that the registration was cancelled on February 5 2016 because the owner did not file an acceptable Section 8 declaration. Because the goods are limited to specialized software for language processing, a similar name used for unrelated products—say, clothing or food—would be far from the scope shown here, while another software tool that provides dictionary or translation functions would be the closest area of concern. The history contains no oppositions, cancellations by a third party, or other enforcement actions, so the supplied file shows no visible enforcement activity. I'd treat this as a meaningful concern if you plan a comparable language‑software product, since the cancelled registration still signals that the mark once covered that niche.
