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.
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.
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.

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

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.
