Lamp for patent attorneys

Draft the opinion. Keep the judgement.

Lamp drafts the Written Opinion on novelty and inventive step, claim by claim. Every finding cites the prior art by number and quotes the passage it rests on. Lamp checks each quote against the patent text, so you know which lines to read first.

Written Opinion

Claims 1–5: novelty and inventive step

Basis D1 and D2 from the Search Report

Application
Hinge for a foldable display device, claims 1–5 as filed
D1
US application
D2
WO application

Novelty assessment each claim against D1 and D2

ClaimStatusCitationReasoning
1 Not new D1 D1 shows the base, both swing arms, the gear train and the flat support plates.
2 Not new D1 D1’s swing arms turn on arc-shaped rails in the base.
3 Not new D1 D1 holds the arms in intermediate positions with a cam and a spring.
4 New D1, D2 D1 folds the display into a U shape. D2 has no gear train.
5 New D1, D2 Neither document delays the tilt of the support plates.

Summary. Claims 1–3 lack novelty over D1. Claims 4 and 5 are new.

Inventive step assessment problem-solution approach

Closest prior art
D1. It shares the most features with claim 1.
Distinguishing features
  • Claim 4The support plates tilt to leave a teardrop-shaped space when folded.
  • Claim 5A pin in a curved slot holds back the tilt until the arms reach 60°.
Objective technical problem
How to fold the display without creasing it at the bend.
ClaimStatusReasoning
4 Obvious D2 tilts its support plates into a teardrop space to stop the screen creasing. Adding this to D1 is obvious.
5 Open No document suggests delaying the tilt. Left for your assessment.
D2, WO application, cited for claim 4 Verified

“When the device is folded, the two support plates tilt toward each other, so that the bent portion of the screen forms a teardrop shape and no crease is formed.”

Industrial applicability
Claims 1–5 can be made and used in industry.
Clarity
Claim 3: “intermediate position” is not defined. Consider an angle range.

A drawing of a Written Opinion, not a screenshot. D1 and D2 stand for the patents it cites, taken from your Search Report. Names and numbers are invented.

Where the hours go.

The reading is the work. These three parts of it take the most time and forgive the least.

  • Every claim, against every document.

    Claim 1 against D1, then against D2, then claim 2. Five claims and two documents make ten careful readings before you write a word.

  • A wrong quote costs trust.

    Cite D1 for a feature it does not show, and the examiner or the client notices. Every citation has to hold up against the text.

  • Inventive step takes longest.

    Pick the closest prior art, name the distinguishing features, frame the problem. Get one step wrong and the argument falls with it.

From claims to a draft opinion.

Four steps, in the order you would work by hand.

  1. Describe the invention

    Start a research session and paste the application's claims into the chat. Then say what to look for in plain words.

    For example: hinge for a foldable phone, support plates tilt to leave room for the bent display

  2. Run a Search Report

    Lamp breaks your claims into features and marks each document X, Y or A for each claim. The closest documents become D1 and D2.

    For example: D1 is X for claims 1 to 3. D2 is Y for claim 4.

  3. Draft the Written Opinion

    Lamp estimates the credits from the patents you select and the AI model you use. Then it assesses novelty and inventive step for each claim, and industrial applicability and clarity.

    For example: Written Opinion on 2 patents: about 400 credits with Claude Sonnet 5.5

  4. Check, then decide

    Read each finding next to its quote. Pin the cited patents side by side, and ask the AI chat when a passage is unclear. The conclusions are yours.

    For example: Claim 5 is open, for your assessment.

Check every finding against the source.

Quoted passages

Every quote is checked against the patent text.

Each finding cites a document by number and quotes the passage it rests on. Lamp looks for every quote in the text of the cited patent.

A quote it finds is marked verified. One it cannot find is marked quote not found. A patent number it cannot confirm is marked unverified. Read the flagged findings first.

Written OpinionClaims 3 and 4, cited passages
  • Claim 4D2 WO application Verified

    D2 tilts its support plates to leave a teardrop space for the bent screen.

    “…the two support plates tilt toward each other, so that the bent portion of the screen forms a teardrop shape…”

  • Claim 3D1 US application Quote not found

    D1 holds the arms in intermediate positions with a cam and a spring.

    “…the cam and the spring hold the rotating arms at any angle between the open and the closed position…”

    Lamp could not find this passage in D1. Read D1 before you rely on the finding.

  • VerifiedThe quote is in the patent text.
  • Quote not foundCheck it by hand.
  • UnverifiedThe patent number is not confirmed.

What a report costs

A report costs credits. How many depends on the AI model you choose and on how many patents you select for the report. The table shows the estimate for each model.

Pro costs €119 a month, or €1,190 a year, and includes 700 credits every month. Unused monthly credits do not carry over.

Max costs €269 a month, or €2,690 a year, and includes 1,800 credits every month. Unused monthly credits do not carry over.

While a report runs, Lamp holds its estimate. When it ends, Lamp charges the credits for the text the model actually read and wrote. That can be less or more than the estimate.

When your credits run out, chat and reports stop until you buy extra credits or your monthly credits refill. You can still open and read everything you made before.

The free trial includes 300 credits and 1 report. Prices exclude VAT.

Lamp drafts. You decide.

Every report says so: it is AI-generated and may contain errors. It does not constitute legal advice. Verify all findings independently.

It can be wrong.
A feature can be read too broadly. A quote can be real and still not support the finding. Read the draft the way you read any first draft.
Every finding has a source.
Each finding names its document and quotes its passage. The verification mark tells you which quotes Lamp found in the patent text.
It is not legal advice.
The report is a research draft. The advice is what you write after you have checked it.
The signature is yours.
Lamp writes the draft. The judgement, and the name on the opinion, stay with you.

Questions attorneys ask.

Can I send the Written Opinion to a client as it is?

No. It is a draft for you to check and correct. Every report says it is AI-generated, may contain errors and does not constitute legal advice.

What does “verified” mean on a quote?

Lamp found the quoted passage in the text of the cited patent. A quote marked quote not found could not be matched, so check it by hand. A patent number marked unverified could not be confirmed. Verified means the words are there. Whether they support the finding is for you to judge.

Where do D1 and D2 come from?

From a Search Report you run in Lamp. It breaks your claims into features and marks each document X, Y or A for each claim. The Written Opinion assesses your claims against those documents.

Can I work from my own documents?

Yes, as text. Paste the application or a client’s disclosure into the chat: Lamp takes the subject brief from it and checks the patents it finds against that brief. There is no file upload. This works on every plan, including the trial.

Try it on a case you know well.

Paste the claims of an application you have already opined on. Compare Lamp’s draft with your own. Lamp is not open to new accounts yet. Your free 14-day trial starts when your account opens.
