You are a brand protection analyst at a sportswear company. You need to track what your three main competitors, NovaSole Inc., VeloGrip Corp., and TrailEdge Ltd., are filing across the US and EU. When a competitor files a new mark in your core classes (25, 28, and 35), you want to know as soon as it syncs. This guide shows how to build competitor monitoring using the Signa API.

Prerequisites

  • A Signa API key with trademarks:read scope
  • Competitor company names or owner IDs

1

Identify competitor owner records

Start by searching for each competitor’s owner profile. The owner entity in Signa consolidates all filings under one canonical record, even when name variants exist across offices.
Expected output:
If a competitor has subsidiaries or name variants, use the owner detail endpoint to check aliases[] for alternate names the API has resolved. This prevents you from tracking an incomplete picture.
2

Review each competitor's portfolio profile

Pull the full owner detail to understand each competitor’s filing patterns, top classes, jurisdictions, and preferred attorneys.
Expected output:
For per-class, per-jurisdiction, or per-year breakdowns, list the competitor’s marks with GET /v1/owners/{id}/trademarks (filtered by nice_classes, offices, or filing_date_gte) and aggregate the results client-side. The owner detail response does not carry a pre-broken-down ranked list; the trademark list is the source of truth for that.
3

List recent filings by competitor

Pull each competitor’s most recent filings to see what brands they are pursuing right now.
Expected output:

Aggregate filing trends over time

Use search with aggregations_only to get filing volume trends without downloading individual records. This is useful for quarterly competitive reports.
Expected output:
A sudden increase in figurative marks might indicate a competitor is developing new logos or brand identities, often a sign of upcoming product launches. Word mark filings in new jurisdictions suggest geographic expansion plans.

Monitoring competitors going forward

The steps above are a good one-time or quarterly audit. For ongoing monitoring, create an owner watch for each competitor owner ID and register a webhook: Signa evaluates the watch against every data update and pushes an alert the moment a tracked competitor files, so you are not re-running searches to find out. If you want to pull results yourself instead, rerun the owner-trademarks query on your own schedule and diff the result against the previous run:
To catch brand-new entrants you are not yet tracking, run a class-filtered search over the same window and exclude the owners you already know about:

Building a competitive dashboard

Combine the above queries into a periodic report that tracks:

What’s next

Trademark Clearance

Run a clearance search against your competitors’ marks before launching a new brand.

Opposition Tracking

Monitor TTAB proceedings where your competitors are involved as parties.

M&A Due Diligence

Evaluate a competitor’s full IP portfolio if an acquisition is on the table.
