The problem

Hours with a highlighter, and the wrong-branch term still gets through

Before filing, the senior paralegal proofs the draft by hand: a printout, a highlighter and a claim tree sketched on a pad. Each claim is read against its parents, each reference numeral ticked against the drawing sheets, and each claim term searched for in the description.

The errors that slip are structural. A term introduced in one claim and used with a definite article in a claim on another branch looks fine to a reader going in order, because the earlier claim was just read. A dependent claim that points to a later claim, or a medium claim hanging off a method claim, hides the same way. Each miss becomes an indefiniteness rejection, a certificate of correction after grant, or a scope problem no certificate can fix.

  • Antecedents
  • Numerals
  • Drawings
  • Support
  • Senior paralegal hours per draftClaims, numerals and support read line by line
  • Rejections that cost a roundIndefiniteness is among the rejections examiners raise most

The Solution

  1. The claim tree as writtenEach claim under its parent, so a borrowed term shows as a broken link
  2. Numerals matched both waysEach reference numeral named in the text and shown in the drawings
  3. Support for each claim termEach term found in the description, with the paragraph cited
  4. Scope decided by a lawyerClerical fixes go to the paralegal; scope fixes go to the attorney

Built-in controls

  • Agents never edit the draft or a drawing
  • Only the attorney changes claim scope
  • Drafts stay inside the firm’s workspace

Check by check

How patent proofreading software reads one draft, check by check

From the first agent pass to the attorney’s signature, each check says who may act on what it finds.

  1. 01Agents proofing the draft

    Agents read the claims, description and drawings in one pass

    How it works

    • The desk strip shows each application in the queue, its claim count, filing date and status
    • 26 claims, 58 paragraphs and 4 drawing sheets read in one pass
    • 7 antecedent issues, 24 numerals with 5 mismatches, 48 claim terms looked up
    • Proof again re-runs each check and keeps each decision already made

    Senior patent paralegalKnows which of the six drafts on the desk to open first, and where its errors sit, before turning a page of the printout.

  2. 02Claim tree, claim 14

    A claim tree drawn as written, with borrowed terms as broken links

    How it works

    • Each claim drawn under the claim it depends on, exactly as the draft words it
    • Each definite term checked against its own claim and its parents only
    • A dashed line runs from claim 14 to claim 9, the only place the controller is introduced
    • Accepting a controller clears the node and the line

    Senior patent paralegalGets the wrong-branch errors she could only find by sketching the tree on a pad, each with its claim, its branch and the reason.

  3. 03Dependency, claim 19

    A dependency check that proposes the likely parent for the attorney

    How it works

    • Flags a claim that depends on a later claim, on itself or on another kind of claim
    • Proposes the likely parent from the terms the claim uses: claim 17 for claim 19, now under the later claim 21
    • Claim 25, a medium claim, hangs off method claim 18 and moves to claim 23
    • A dependency fix changes scope, so the paralegal can only send it on

    Patent attorneySees each broken dependency with its likely parent and the term that points to it, and settles it before an examiner objects.

  4. 04Numeral check

    Reference numerals matched both ways, text to drawings and back

    How it works

    • All 24 numerals matched, each row with the element named, its paragraphs and its figures
    • The mismatched filter shows 7 rows behind 5 mismatches
    • Numeral 130 names both the expansion valve and the bypass valve
    • The bypass valve becomes 134, the numeral FIG. 1 already gives it

    Patent agentSees exactly which numeral was reused or mistyped, and in which paragraph, while the fix is still one word in the text.

  5. 05Drawing sheet 2

    Each drawing sheet, with the callouts the text never names circled

    How it works

    • Each drawing sheet shown with its callouts as the drafter drew them
    • A circled callout has no match in the text: FIG. 2 labels the fan 116, the text calls it 118
    • Clicking a callout opens the paragraphs that name it
    • Accepted drawing fixes go to the drafter as corrections on the sheet

    Senior patent paralegalStops ticking numerals against four printed sheets, and sends the drafter a marked correction in place of an email describing it.

  6. 06All issues by type

    One issue list: each fix, its source and who may decide it

    How it works

    • Each of the 15 issues and 2 warnings shows the words as written, the proposed fix and its source line
    • Antecedent and numeral fixes are clerical, so the paralegal may accept them
    • She ticks the clerical fixes she has read and accepts them together
    • Scope fixes go to the attorney in one step

    Senior patent paralegalClears twelve clerical fixes in one sitting and sends on only the five decisions that need a lawyer.

  7. 07Claim term support

    Support for each claim term, cited to its paragraph

    How it works

    • All 48 claim terms looked up: 41 verbatim, 6 in close wording, 1 with none
    • Each match cited to its paragraph
    • Claim 13’s hydrophobic coating has none; the closest is a frost-resistant coating, in paragraph 0042
    • The attorney amends the claim, or asks the inventor before adding support

    Patent attorneyChooses between amending claim 13 to the description’s own words and adding support, with the cited paragraph on screen.

  8. 08Fixes and markup

    A marked-up Word file carrying only the accepted fixes

    How it works

    • Each fix listed with who decided it, when and why
    • Only accepted fixes are applied, here as 14 tracked changes
    • Rejected and undecided fixes stay out of the document
    • The 2 drawing corrections go to the drafter on their own

    Patent agentOpens one file showing each change against the draft they wrote, with the claim and the decision behind it.

  9. 09Ready to file

    A ready-to-file check the attorney signs, traced to each decision

    How it works

    • Nine checks: every issue decided, no broken links, numerals matched, each term supported
    • Claim count and fees, an abstract of 142 words, the title and the sheets
    • The attorney signs once the first 8 pass; the agents file nothing
    • 38 minutes of people’s time, against about 4 hours for the same proof on paper

    Patent attorneySigns a check that traces item by item to the decisions behind it, on the day the draft reaches the desk.

Around the proof

More of the patent proofreading software, from citations to settings

Six more screens: a citation, a drawing sheet, the attorney’s queue, a kept warning, the record and the settings.

The claim behind a citationEach citation opens what it was read from. Claim 9 as written, on its branch from claim 1 through claim 8, is where the controller first appears.
A numeral no paragraph namesFIG. 3 shows a tank probe labeled 142 that the description never mentions. The fix adds it to paragraph 0037 as a clerical change.
The attorney’s five decisionsSwitched to the attorney, the list narrows to the two dependencies, the support gap and the two warnings the paralegal sent on.
A warning kept with its reasonSubstantially is a relative term. The description gives the standard, so the attorney keeps the word and records why.
Each run and decision, in orderAgent runs, decisions and their reasons, the markup and the signature, newest first. No entry can be changed afterward.
Which checks run, and who decidesThe practice chair sets each check as a defect or a warning, and which fixes the paralegal may take and which stay with the attorney.
Proposals only

Six agents read and propose; only people change the draft

Each reads one thing and proposes. The paralegal and the attorney decide.

Questions on claim trees, numerals and who signs

What is patent proofreading software?

Patent proofreading software reads a draft application before filing the way an examiner will. This one draws the claims as the tree they really form, checks each antecedent on its own branch, matches reference numerals between the text and the drawings, and finds support for each claim term, with one cited fix per issue.

How does it catch an antecedent basis error that reads fine in order?

It checks each term against its own claim and the claims above it on its branch, and nothing else. A term introduced on another branch does not count, so a claim that borrows it shows on the tree with a dashed link to where the term really lives.

Does it change the draft or the drawings?

No. Agents propose and people decide. The marked-up Word document is a separate copy carrying only the accepted fixes as tracked changes, and drawing corrections go to the drafter as a marked sheet.

Who decides a fix that changes claim scope?

The attorney of record. Dependencies, support gaps and warnings go to the attorney, and the firm’s settings say which fixes count as clerical. The attorney also signs the ready-to-file check.

Can it re-proof claims amended after an office action?

Yes. An amendment goes through the same checks, and only the amended claims and their branches are checked again. Anything that looks like new matter goes to the attorney.

Does a client’s draft ever train a model?

No. Drafts stay inside the firm’s workspace, and the proof record, from the first agent run to the attorney’s signature, is filed with the matter.

Let the tree show the borrowed term
before an examiner does.

A draft that drew an indefiniteness rejection is the best test: we’ll show you its claim tree, its numerals and its support table.
