Frequently asked questions
- What is post-issue patent proof reading?
- Post-issue proofreading is the review of a granted U.S. patent, after its issue/grant date, to identify clerical, typographical, or publication errors in the issued patent so they can be corrected through a Certificate of Correction.
- Why does post-issue proof reading matter?
- Errors in an issued patent can undermine enforceability and value, and early correction is the last low-cost opportunity to fix them before the patent is relied on in licensing or litigation.
- How does Erlich help?
- Erlich compares issued patent text with filed documents in seconds, highlights meaningful differences, helps users quickly classify material impact, and generates a ready-to-file Certificate of Correction—reducing hours of error-prone work to a fast, reliable workflow.
- How does Erlich work?
- Enter the patent application or the granted patent number.
- Erlich fetches all relevant docs while you sip your coffee.
- Erlich then shows you a list of all differences asking you to review and select the ones to be included in the Certificate of Corrections.
- If required, you can export the Certification of Corrections.
- Can I try before I buy?
- Yes, your new account comes with trial credits so the first few reviews are not charged.
- Are separate licenses required if I invite my colleagues to Erlich?
- No. There are no seat or user based licenses. You or your team only pay for the number of reviews you do.
