What goes wrong with intellectual property exhibits, and how it is handled
What goes wrongPatent drawings and claim columns leave little blank space for a stamp.
How ExhibitPrep handles itDrag the stamp anywhere on the page or choose a preset; the preview shows the page you will download, so the stamp can be kept clear of signatures, figures and existing page numbers.
What goes wrongDozens of prior-art references need sequential labels in the order the chart cites them.
How ExhibitPrep handles itBatch stamping applies sequential labels across the whole set — 1, 2, 3 or A, B, C — from the starting value you choose, in the document order you set.
What goes wrongThe file history is one long document that the brief cites by page.
How ExhibitPrep handles itBates numbering adds page numbers with the prefix, starting number and zero padding you set — ABC-001 onward — and the count continues across the documents in a set or restarts in each file.
What goes wrongConfidential technical material cannot be uploaded to be stamped.
How ExhibitPrep handles itDocument bytes are processed locally in your browser and are not uploaded to our servers.

Frequently Asked Questions
How should I label intellectual property exhibits in Massachusetts?
Use Numbers (1, 2, 3...) for plaintiff exhibits and Letters (A, B, C...) for defense exhibits, per Mass. R. Civ. P. 16. Under Superior Court Rule 9A, the pages of exhibits attached to a motion must be consecutively numbered. ExhibitPrep's Intellectual Property templates apply the right prefix automatically, so you're not re-deriving the local convention on every filing.
When do I have to exchange intellectual property exhibits in Massachusetts?
Massachusetts sets the exhibit exchange window at 10 days before trial (Mass. R. Civ. P. 16), though the exact date can shift with your assigned judge's scheduling order. Confirm the deadline in your case's pretrial order before you start stamping, then batch-process the full intellectual property production in one ExhibitPrep session once it's locked in.
What e-filing system handles intellectual property exhibits in Massachusetts?
Massachusetts runs electronic filing through eFileMA. Check the current upload cap before filing (Superior Court covered civil filings: 25 MB per document / 50 MB per…), export each exhibit as a text-searchable PDF, and split any long registration documents into separate files so a single scanned record doesn't blow past the limit.
What exhibits come up most in a Massachusetts intellectual property case?
Intellectual Property matters in Massachusetts typically turn on registration documents, prior art, infringement evidence, plus whatever case-specific records the dispute calls for. Under Superior Court Rule 9A, the pages of exhibits attached to a motion must be consecutively numbered. Stamp them all inside ExhibitPrep using the matching plaintiff or defense template, so every exhibit in the production carries a consistent, consistent exhibit mark before it goes to opposing counsel.
Can I stamp a large intellectual property production for Massachusetts courts?
Yes. The Day Pass ($14.99) gives you unlimited stamping for 24 hours, which covers hundreds of exhibits in a single intellectual property case. Processing runs entirely in your browser, so your Massachusetts case files never leave your computer. That matters here because e-filing upload caps (Superior Court covered civil filings: 25 MB per document / 50 MB per…) often force a large production into multiple separate uploads.
