Frequently Asked Questions
What patent databases does the tool search?
The patent database search covers USPTO patents, international PCT patents, and major foreign patent offices. However, for exhaustive prior art searches, you should supplement with specialized patent search engines like Google Patents or Espacenet.
Are the claim charts admissible in court?
Claim charts generated by the tool are excellent working documents and valuable for infringement analysis. However, you must verify accuracy and may need expert testimony to introduce them in court proceedings.
How current is the trademark data?
Trademark data is sourced from USPTO and international trademark offices and updated regularly. Check for very recent applications directly on the USPTO database before making final decisions.
Can I use prosecution history admissions in litigation?
Admissions from patent prosecution records (like narrowing amendments and applicant remarks) are generally admissible as judicial admissions in litigation. However, consult patent litigation specialists about strategic use.
