01
Patent Litigation
Complex infringement and defense actions in U.S. federal courts — claim construction, validity, damages, trial, and appeal.
02
Post-Grant & PTAB
IPRs, PGRs, and reexaminations, coordinated with parallel district-court litigation and portfolio objectives.
03
Licensing & Monetization
Enforcement-backed monetization, licensing program design, and acquisition and divestiture support.
04
Strategic Patent Analytics
Claim-strength scoring, portfolio prioritization, landscape mapping, and litigation-readiness analysis.
05
Advisory Services
Executive- and expert-ready guidance for boards, investors, and licensing counterparties.
06
Industries & Technologies
Pharmaceuticals and life sciences to software, wireless, semiconductors, and AI-driven systems.
Proprietary Technology
Diligence at machine scale. Judgment at partner level.
K2K runs its own proprietary AI patent-diligence engine — custom-built in-house and refined on live monetization campaigns. Every U.S. patent in a portfolio is scored against a multi-dimensional rubric spanning legal exposure, technical merit, market adoption, and enforcement posture — calibrated to the current PTAB discretionary-denial regime and checked against live litigation data.
Portfolio triage — every asset scored, tiered, and rankedClaim-level analysis — risk decomposition with partner review
01
Portfolio triage in days, not quarters
Every asset scored, tiered, and ranked — enforce, license, hold, or divest — with settlement-ready candidates flagged early.
02
Claim-level AI analysis
Claim scope and construction risk, §101 and §112 exposure, prior-art density, and prosecution-history red flags — assessed to district-court and PTAB standards.
03
Live litigation signal
Venue analytics, PTAB outcome data, and funder-grade damages screens, refreshed as the law moves.
04
Deal-ready output
A scored portfolio workbook and a partner-authored memorandum — ready for boards, funders, and counterparties.
The machine ranks. The partners decide. — the same engine that runs our own monetization campaigns.

Patent Monetization
A patent portfolio is an asset, not an expense.
We help operating companies, inventors, and funds convert patents into revenue — structuring the vehicle, the capital, and the risk transfer behind every monetization, from pre-suit diligence through resolution. Monetization is a sequence of decisions: what to assert, how to structure it, who funds it, and how the risk is carried. We run every step.
1
Diligence & Valuation
Map the portfolio against external markets — engine-scored, partner-confirmed.
2
Portfolio Sorting
Separate defensive patents from the ones that earn — adoption, term, family depth.
3
Structuring
In-house campaign or dedicated vehicle — we build either, and say which fits.
4
The Vehicle
A holding company that ringfences assets and isolates countersuit risk.
5
Capital
Non-recourse funding from leading patent funders — planned at the start, not month nine.
6
Risk Transfer
Judgment-preservation and litigation insurance that de-risk and unlock financing.
7
Enforcement
Milestones that move the deal — filing, Markman, IPR survival, summary judgment.
8
Returns
Waterfall economics that pay the owner at the first license — not only after the funder.
What machine-scale scoring changes about monetization
Traditional diligence prices a portfolio by sampling it. Machine-scale scoring reads all of it — which changes what gets asserted, what gets divested, and what a funder will underwrite. The economics of triage move first; the law moves with them.
PTAB & Post-Grant
Enforcement timing after the discretionary-denial shift
The post-2025 discretionary-denial regime rewrote the IPR calculus — settled expectations and forum timing now shape which patents can realistically be put to work, and when. Portfolios scored under the old assumptions deserve a second read.
Litigation Finance
What funders actually underwrite
Capital doesn't buy claims; it buys verifiable damages, clean chain of title, and venue realism. Portfolios packaged to that standard — engine-scored, claim-charted, insurance-ready — clear investment committees that narrative decks never reach.
