USPTO hosts the design patent figures at predictable URLs keyed by patent number. An image mapping in SleekRank constructs those URLs from the D-number field, so figures load directly from the USPTO image server with no need to mirror the files locally. If USPTO's image endpoint is slow, cache the figures to S3 or Cloudflare R2 and use that mirror URL instead.

Locarno is a hierarchical classification - 02-04 means class 02 (apparel and haberdashery), subclass 04 (footwear). Use the field directly as a category filter via the sleekRankRelatedEntries helper, which surfaces sibling D-numbers sharing the same Locarno code. Each page automatically links to up to six related designs without per-record curation.

Hague Agreement filings are published by WIPO and indexed in WIPO's DesignDB. SleekRank can run a second page group at /hague-design/{slug}/ pulling from the WIPO XML feed. The two corpora interlink: a US design patent can show its corresponding Hague registration if the inventor filed both.

Yes. Design patents have one claim - typically "the ornamental design for [article] as shown". That single line plus the figures is the entire grant. Render the claim text in a dedicated block under the figure gallery; the field comes through the bulk XML and renders via a tag mapping.

Design patents have a 15-year term from grant. Add an expiry_date field derived from the issue date, and use a selector mapping to show an expired badge when the term has passed. Expired designs are still valuable for prior-art and historical research, so keep them in the corpus with the badge rather than de-listing.

Both index design patents but treat them as text records with figures behind a click. SleekRank renders the primary figure in the hero and the full figure gallery inline, which matches how design patent searches actually look. The figures are public from USPTO, so there is no licensing constraint on rendering them on the operator's domain.

Yes. Add a secondary data source keyed by D-number for custom renders, 3D model files, or editorial annotations. SleekRank merges secondary sources on the same slug, so the per-patent page can carry both the USPTO figures and the operator's own design analysis assets.

Each design patent record is smaller than a utility patent since there is no detailed description - typically 1-2 KB per record, plus references to figure URLs hosted at USPTO. One million records is 1-2 GB in the items table, which fits comfortably on any production WordPress database with room to spare.
