Weekly competitor patent radar in Slack

Build me a competitor patent radar that runs every Monday at 8:00am on a cron trigger.

Inputs I should be able to configure: (1) a list of competitor company names to use as patent assignees, (2) the Slack channel to post the digest to, and (3) the lookback window (default 7 days).

On each run, use USPTO PatentsView to find new filings from those competitors in the lookback window:

1. Call Search Granted Patents filtered to those assignees with patent_date in the last 7 days. Pull patent_id, patent_title, patent_abstract, patent_date, assignees, and inventors.

2. Call Search Pre-Grant Publications filtered to those assignees with filing_date in the last 7 days. Pull document_number, publication title, abstract, filing_date, assignees, and inventors.

3. For each granted patent, call Get Granted Patent Brief Summary (and Get Granted Patent Claims if the brief summary is empty) and write a 2-3 sentence plain-English summary of what the invention actually does.

Reminder on PatentsView usage: every request needs the q parameter, sort fields must be listed in f, withdrawn patents are excluded by default, and the active host is search.patentsview.org/api/v1.

Then post a single digest message to the configured Slack channel using Send a Message. Group entries by competitor (one section per assignee). For each filing show:

- The patent title as a link to the USPTO record (https://patents.google.com/patent/US{patent_id} for grants, https://patents.google.com/patent/US{document_number}A1 for pre-grant pubs)

- Assignee name

- Inventor names

- Filing date or grant date, and whether it is a granted patent or pre-grant publication

- The 2-3 sentence plain-English summary

Use Slack mrkdwn formatting (*bold* for competitor headers, <url|text> for links). Cap each summary at 3 sentences so the digest stays scannable.

If no new filings dropped that week, still post a short message to the channel like "No new patent filings from your watch list this week." so the channel knows the radar is alive.
