Annotra
Annotate Figures In-House

Annotate patent figures in-house.

Skip the drafting invoice. Annotating figures you already have does not need an outside vendor or a new quote - add the callouts yourself and export a filing-ready PDF.

  • Start from the drawings you have

    Upload the PDF you already hold. Annotra adds reference numbers and leader lines to it rather than redrawing it.

  • Bring in whoever you need

    Invite an illustrator, an attorney or a colleague onto a project. They work on the same figures without a subscription of their own.

  • A filing-ready PDF at the end

    Export clean, professionally annotated drawings as a high-resolution PDF, ready to go into the application.

Reviews

From the peoplepreparing the drawings.

  • What used to take an hour now takes minutes.

    Annotra has completely changed how I handle reference numbers and leader lines. It's fast, intuitive, and built around the way patent figures actually need to be prepared.

    Rachel BennettPatent Illustrator, 15+ Years Experience

  • I wish I had this years ago.

    I used to annotate every figure manually in Illustrator. Annotra makes the entire process dramatically faster, especially when working with multiple figures and repeated reference numbers.

    Thomas CaldwellPatent Agent, Independent Practitioner

  • The learning curve was practically nonexistent.

    I uploaded my figures, imported my reference numbers, and was working within minutes. It eliminates a surprisingly tedious part of preparing a patent application.

    Daniel MercerPatent Attorney

  • Simple, focused, and incredibly useful.

    Annotra doesn't try to replace my drawing software. It does one specific job extremely well: getting reference numbers and callouts onto patent figures quickly and consistently.

    Emily HartwellPatent Agent

  • A huge time saver for figure preparation.

    Being able to annotate an entire set of drawings, keep everything organized, and export a clean PDF from one place has made my workflow much more efficient.
