How to read this
Every row here is an application — a request the USPTO has not yet decided. In plain English: these filings show where Pfizer Inc.’s R&D effort is pointed right now, often 18–24 months before any product ships — but an application can be amended, abandoned, or rejected, and most confer no enforceable rights until granted. A “granted parent” tag means the filing continues a patent family that already has a grant — the new claims themselves are still pending. Filings are matched by applicant name, so work filed under subsidiary or research-entity names may not appear. Source: USPTO Open Data Portal (public).
