USPTO publishes the TSDR daily transaction file every night, covering filings, status updates, and assignments from the previous business day. A 24-hour SleekRank cache aligned to the import means status changes show up on your site one day after USPTO records them - same lag as TSDR itself for any practical use.

Yes. The TSDR feed carries the design-code categories per mark. Render them as filterable facets and link each design-code value to a /design-code/{code}/ page group that lists matching marks. The mark image itself is available as a per-serial-number JPG from the USPTO endpoint, embedded via image mapping.

Madrid Protocol filings come in via TSDR with the 79-series serial prefix and appear in the same daily feed. They render through the same template; the owner address often shows a non-US country, which you can use to drive a country-of-origin filter on the corpus.

TSDR exposes the trademark assignment record as a separate feed. Link the assignment data to the serial number, then render the chain of owners as a timeline block in the per-mark template. Past owners become links to their respective /trademark/owner/{slug}/ pages so the ownership history is navigable.

Yes. Abandoned and cancelled marks are valuable for clearance searches and trademark research. SleekRank keeps the page live with a clear status flag, so historical record-keeping persists. The sitemap can optionally exclude abandoned marks to focus crawl budget on live ones.

Yes. Use a separate WordPress post type keyed by serial number for attorney notes, then have SleekRank merge that into the per-mark page render. Notes stay editable in WordPress; the bibliographic data stays bound to TSDR. The combination is what private trademark databases sell at premium prices.

Trademarkia and Justia are themselves USPTO mirrors with their own templates. Scraping them is fragile and likely violates their terms. TSDR is the public source they both pull from, available as bulk data under USPTO's open data policy. SleekRank reads TSDR directly, so the corpus is upstream of any aggregator and not dependent on their continued operation.

Each resolved trademark record runs about 3-8 KB in the SleekRank items table depending on classes and assignment history. Five million records is a 20-40 GB MySQL footprint, fine on a standard managed database. Most production setups start with a class-filtered subset and expand as the indexing budget grows.
