The answer, as recorded

Searched. One caveat up front: this niche is heavily SEO-farmed, and several "best of 2026" listicles that surface are thin affiliate content that invent rankings and pricing. So I'm weighting established vendors and primary sources, and I'll flag the shakier ones. Also worth naming the real scope: for a startup, "IP monitoring" almost always means **trademark watch + domain/impersonation monitoring**, sometimes **marketplace counterfeits**, and rarely patents. Here's what I'd actually use, in order: ## Start here (free, do it this week) **1. USPTO TSDR + TEAS email alerts** - official status change notifications on your own applications/registrations. Free, authoritative, and catches office actions and deadlines you cannot afford to miss. Not a watch service - it only covers marks you own. ([tsdr.uspto.gov](https://tsdr.uspto.gov/)) **2. WIPO Global Brand Database + EUIPO eSearch** - free manual searching across international registers. Good for a quarterly self-check on conflicting filings before you pay anyone. **3. Google Alerts + a domain watch** - set alerts on your brand name and common misspellings. Cheapest possible detection of copycat sites and typosquats. Pair with registrar-level monitoring if you're on Cloudflare/Namecheap. ## Paid trademark watch (the real answer for most startups) **4. Markify** - the one I'd name first for a funded startup. Purpose-built automated watch with strong fuzzy/phonetic matching, priced for companies that aren't Fortune 500. This is the usual sweet spot: you want to know when someone files a confusingly similar mark, ideally in time to oppose during the publication window. ([sourceforge.net comparison](https://sourceforge.net/software/product/Markify/alternatives)) **5. Your trademark attorney's bundled watch service** - genuinely underrated. Firms like Gerben IP or your existing counsel resell a watch and, critically, *triage the results*. Raw watch feeds generate a lot of noise; the value is someone telling you which of 40 hits actually warrants a cease-and-desist or opposition. If you have counsel, ask them before buying software. **6. Corsearch** (which absorbed TrademarkNow) - the step up when you have a real portfolio across multiple jurisdictions, or you're doing clearance searches for new product names regularly. Quote-based, and overkill if you have three marks in one country. ([corsearch.com/trademark-solutions/trademark-watching](https://corsearch.com/trademark-solutions/trademark-watching)) **7. Clarivate CompuMark** - the enterprise/law-firm standard for watching and clearance. Name it only if you're post-Series B with international expansion underway. ## If you sell physical products **8. Red Points** - best-known for automated marketplace takedowns of counterfeits and unauthorized sellers across Amazon, eBay, Alibaba, social. This is the category where automation genuinely pays for itself. **9. MarqVision** - AI-driven competitor to Red Points, same problem space, often quoted more aggressively for smaller brands. Worth putting both in a bake-off. ([marqvision.com comparison](https://www.marqvision.com/blog/brand-protection-tools)) Also: **Amazon Brand Registry** is free with a registered trademark and should be step zero if you sell on Amazon. ## If your risk is impersonation/phishing, not counterfeits **10. BrandShield** or **Bolster/Doppel** - fake login pages, spoofed domains, fraudulent social accounts, fake app listings. This is the fintech/SaaS version of the problem, and it's a security spend more than a legal one. ([sourceforge brand protection listing](https://sourceforge.net/software/brand-protection/for-small-business/)) ## Patents (usually skip early) **11. Google Patents alerts** or **Lens.org** - free, sufficient for keeping an eye on a competitor's filings. Step up to **PatSnap** or **Questel** only if you're deep tech with an actual patent strategy; both are expensive and hard to justify pre-revenue. --- **My concrete recommendation:** TSDR alerts + Google Alerts today (free), Markify or an attorney-bundled watch once you have a registered mark (low hundreds to low thousands per year), and Red Points/MarqVision only if you're shipping physical goods. Ignore anything quoting $8,000-$40,000/year as the entry price for AI trademark monitoring - I saw that figure on a low-credibility site and it reflects enterprise multi-jurisdiction contracts, not what a startup needs. Two vendors surfaced that I'd verify carefully before trusting - "GleanMark" and "MarkWatch" - both appeared with suspiciously promotional free-tier pitches and I couldn't confirm they're established operations. Treat as unvetted.
