Success Story

How Lumenci charted a semiconductor portfolio from public documents alone, and helped close the sale

 

Semiconductor patents are hard to evaluate and harder to prove from the outside. Lumenci built six claim charts from public documentation alone, credible enough to carry the portfolio through acquisition talks.

Result

Six semiconductor claim charts a buyer could trust before signing anything, and a portfolio that sold.

Semiconductor claims read on things buried inside the silicon. Proving them from public documents alone is a different exercise entirely.

What most teams do.

Build infringement charts from the strongest evidence available, which in semiconductor usually means teardowns, produced materials, or confidential sources. None of that can be shown to a buyer who has not signed anything.
 

What Lumenci did instead.

 Built six claim charts grounded entirely in public-domain documentation, demonstrating claim coverage and infringement direction without a single confidential source.

Why it mattered.

 The broker could put the charts in front of any prospective buyer immediately, with nothing to gate access. The portfolio's value was legible from the first conversation instead of after a signed agreement.

How It Was Done

Lumenci worked as the broker's technical team on the sale, staffed with semiconductor and analog specialists and analysts who know what a buyer's own technical reviewer will look for in a chart.

Claim chart preparation

Six charts were built entirely from public-domain technical documentation, showing claim coverage, novelty, and infringement direction for the strongest assets in the portfolio.

Expert validation

 The charts were reviewed with a qualified technical expert to confirm they were sound and ready to stand up in front of a buyer's own reviewers. 

Market context and analysis

 Focused market research established the portfolio's commercial relevance and where it sat within the semiconductor and adjacent technology landscape, so the technical case came with a market case. 

Buyer-facing packaging

 The charts and market analysis were delivered in a form the broker could take straight into buyer conversations, rather than as technical documents needing translation first. 

 What Changed for the Client

Where they stood.

Six defensible claim charts and a market analysis the broker could take to any buyer without gating access behind an agreement

 What Lumenci added.

 A technical case a buyer could evaluate on public evidence, which took uncertainty out of the early conversations and gave the portfolio credibility from the first meeting 

Where it stands.

The portfolio sold, and the broker credited the technical work for helping get it there.

 Semiconductor claim charting and market analysis

We chart semiconductor and analog patents for sale, licensing, and enforcement, including the reads that have to hold on public evidence alone. Our practice is part of an integrated IP services platform spanning reverse engineering, portfolio mining, valuation, and litigation support.
 
 

  

 100k+ Patents Analyzed 

 3200+ Claim Charts Delivered 

 

250+ Litigations Supported 

 What This Would Look Like for Your Matter

A scoping conversation covers the portfolio, whether it is heading to sale or licensing, how much of the infringement case can be built from public documentation, and your timeline to market. You get a view of which assets can carry a buyer-facing chart before committing to a full charting programme. 

Frequently Asked Questions

Can semiconductor infringement be shown from public documents alone?

Sometimes, and it depends on the claim. Where the claim reads on architecture, interfaces, or behaviour that datasheets, standards documents, and technical literature describe, the public record can carry it. Where it reads on internal circuit structure, it usually cannot, and that gap is worth knowing before a buyer finds it.

Why do semiconductor portfolios need charts before a sale?

Because a buyer cannot assess semiconductor claims from the patent text alone. The technology is dense, the claims are abstract, and without a chart showing what the patent reads on in a real product, most buyers will not spend the time to work it out themselves.

What do buyers of semiconductor portfolios actually check?

Whether the claims read on products that are shipping, how defensible that read is, and whether the assets are still relevant to where the industry is going. A chart answers the first two. Market analysis answers the third.

When does a semiconductor portfolio need reverse engineering instead?

When the claims read on structures inside the die that no public document describes. For a sale, that is a different and more expensive exercise, so it is usually reserved for assets going to enforcement. Lumenci provides semiconductor reverse engineering where a matter requires it.

Is claim charting available on its own?

Yes. Claim charting is often the first engagement, for a sale, a licensing approach, or a pre-filing assessment. For a sale it is usually paired with market analysis.

Can Lumenci value a semiconductor portfolio as well as chart it?

Yes. Charting establishes what the patents read on, and valuation turns that into a number a buyer or seller can work with. Lumenci provides patent valuation as a standalone engagement.
