As answered by people managing Codewars and Demarka.
Demarka's answer:
Demarka is a trademark search tool that provides a clear registrability verdict with probability — not just a list of similar trademarks.
It combines trademark search, similarity analysis, and compliance checks to determine if a brand name can be registered, explain risks, and suggest improvements before filing.
Demarka's answer:
Most trademark tools show results. You’re left guessing.
Demarka gives you a clear answer.
– registrability verdict with probability
– risk and conflict explanation
– actionable recommendations
All in under 2 minutes, at a fraction of the cost of traditional checks.
Demarka's answer:
Startups and SMBs validating brand names before launch or market expansion.
Also used by:
– creative and branding agencies validating names for clients
– trademark professionals automating initial screening
– e-commerce and digital businesses launching new brands
Common need: fast and reliable trademark validation without complexity.
Demarka's answer:
Demarka was built by a patent attorney with 15+ years of experience in intellectual property and software development.
In practice, trademark verification required manual work: searching databases, analyzing similarities, checking compliance, and forming a registrability opinion. The process was time-consuming, expensive, and hard to scale.
Demarka automates this entire workflow — and goes further by combining similarity analysis, compliance checks, and probability estimation into a single system.
The idea originated from a previous IP management product, where trademark search and monitoring features attracted the most demand. It became clear that existing tools were either complex databases or expensive manual services.
Demarka was created to provide fast, affordable, and understandable trademark verification — giving clear answers instead of raw data.
Demarka's answer:
– Cloud-based SaaS architecture
– Trademark similarity algorithms (phonetic, linguistic, edit distance)
– Machine learning for pattern recognition
– LLM-based analysis for compliance checks and probability estimation
– Aggregated trademark data from official registries across 90+ countries
Optimized for fast processing and scalable global trademark search.
