What This Replaces

The Offshore Patent ALSP Building Your Invalidity Charts

The work the offshore patent analyst does on every prior-art search and claim chart — and the cost of leaving it there.

The labor

Patent prior-art search and claim charting today moves through offshore patent ALSPs in India and adjacent geographies — Evalueserve, Sagacious, Clairvolex, and similar firms — staffed with technical analysts and patent agents. Per-chart cost runs $1,500–$5,000 depending on technical complexity, claim count, and reference-corpus size. A multi-claim invalidity contention support package can run $20K–$100K all-in.

The cycle time

Standard claim-chart turnaround runs 2–4 weeks at the offshore patent ALSP, with longer cycles when the claim language is unusual or the technical area is fast-moving. Every week the chart isn't on the litigation team's desk is a week the invalidity contention drafts get pushed, the inter partes review filing slips, and the licensee negotiation loses leverage.

Side by Side

Patent Prior Art Today vs. With Last Rev

The numbers that matter: cycle time, per-chart cost, accuracy, and audit posture.

Dimension	Offshore Patent ALSP	Last Rev Patent Prior Art
Cycle time, claim set to claim chart	2–4 weeks per detailed chart	2–6 days
Per-chart unit cost	$1,500–$5,000 per chart	Per-chart, benchmarked at 25–45% of offshore unit cost
Surge handling on multi-claim contentions	Add analysts, queue grows, deadlines slip	Elastic by design — many charts in parallel
Audit log per element-mapping	Analyst notes, no element-level lineage	Source citation + element basis + model version + confidence per mapping
Cross-reference combination analysis	Manual combination memos, time-bounded	Combinations enumerated and scored systematically
Reference-corpus coverage	Bounded by analyst access and search-query design	USPTO + EPO + JPO + KIPO + CNIPA + non-patent literature in one pass
Renegotiation leverage at next ALSP renewal	None — you're locked in	60–85% of routine chart volume off the contract

How It Works

From Claim Set to Invalidity-Ready Chart

Five steps. Every one logged. Every one reversible if your confidence threshold isn't met.

Submission Lands

Patent claims, specification, drawings, and target prior-art corpus from the litigation or IP team. Matter-specific scope, court-rule format requirements, and any prior chart work from the same patent family.

Extraction & Classification

Claim elements parsed and stored in a structured form. Prior-art corpus indexed across USPTO, EPO, JPO, KIPO, CNIPA, and non-patent literature. Element-by-element mapping built with citation pull-through. §102 anticipatory references separated from §103 combinations.

Validation Against Court & Counsel Bar

Mappings validated against the case-team's chart format and court-specific local rules. Anything below your confidence threshold per element-mapping is routed to a human exception queue — your call which queue, ours or yours.

Push to Matter System

Element-by-element claim chart, invalidity contentions draft, IPR supporting analysis, and reference pack delivered into iManage Work, NetDocuments, or your matter system via the documented integration. Excel or Word output per court-rule format.

Audit Log Persisted

Every claim-element mapping, citation, and combination decision logged with the source paragraph, prior-art reference, model version, prompt, and confidence score. Privilege-aware logging; work product stays inside your environment.

Compliance & Defensibility

Built to Meet the Quality Bar Patent Counsel Already Runs On

PTAB and litigation-court rule conformance

Chart formats and reference-pack structures track PTAB IPR petition requirements, federal district court invalidity contention rules (e.g., NDCA, EDTX, DDel local patent rules), and ITC investigation requirements. Court-specific format templates are configurable.

Citation chain of custody

Every claim-element mapping traces back to a specific page and paragraph in the prior-art reference. When opposing counsel challenges a mapping, the audit log produces the citation, the surrounding context, and the basis for the element-by-element call.

Privilege and work-product posture

Claim charts and invalidity drafts are work product. The workflow runs inside your environment with privilege-aware logging — no outbound disclosure to third-party reviewer queues. Outside-counsel handoff preserves the chain when a contention escalates.

Matter confidentiality & data residency

Pre-filing patent strategy and pre-PTAB invalidity work are time-sensitive and confidential. Deployable in your VPC or our SOC 2 environment. Encryption in transit and at rest; retention policies tied to your matter and post-judgment retention rules.

Common Questions

What Patent Counsel Asks About Prior Art Search

PatSnap, Derwent, and PatBase are search and analytics platforms — and we don't compete head-to-head with them. The competitor on this page is the offshore patent ALSP analyst line on your matter budget — Evalueserve, Sagacious, Clairvolex, and similar firms charging $1,500–$5,000 per detailed claim chart. We undercut that labor cost, integrate directly into your existing matter system (iManage, NetDocuments, or proprietary), and deliver claim charts and invalidity drafts in court-rule format. Most clients run patent-research platforms and AI workflows complementarily.

Contract review and M&A due diligence handle commercial paper. Patent prior art is a specialized IP litigation and prosecution workflow — element-by-element claim charting with technical-area expertise and prior-art-specific reference handling. Different scopes, different bar, different deliverables. We built this as a separate page so the workflow stays specific to what patent counsel buys.

Most patent practices keep the ALSP arrangement in place during pilot and early production — we route exceptions, novel technical areas, and chart work that genuinely requires senior patent-agent judgment to the team you already have. Volume to the ALSP drops 60–85% on routine chart work once cutover completes. You renegotiate at the next renewal from a much better position, or shift the relationship to higher-complexity work like patent landscape analysis or freedom-to-operate studies.

Our pilot success threshold is element-by-element mapping accuracy at parity with or above your incumbent ALSP, measured on the same shadow-data sample of claims and references and validated against the case-team's calibration set. Anything below your defined confidence threshold per mapping is routed to a human exception queue — your call which queue, ours or yours.

Technical-domain calibration happens during onboarding with the case team. Domain-specific glossaries, claim-construction conventions, and prior-art reference databases are configured per-matter. We don't pretend to be the technical expert — we apply the case team's claim-construction call and the technical-domain calibration consistently across the chart, with element-by-element evidence so the patent attorney makes the judgment call on a richer file.

Non-patent literature (IEEE, ACM, arXiv) and product documentation (datasheets, manuals, standards documents) are indexed alongside patent prior art. Citation pull-through traces back to the specific page and paragraph; reference packs include exhibit-tagged copies for IPR or invalidity contentions. When the prior art is a hard-to-find product manual, the audit log captures the source and the access path.

Patent prior-art pilots typically run 4–6 weeks: 1 week of integration, technical-domain calibration, and matter-template mapping with the case team; 2–3 weeks of shadow-mode running on a constrained scope (one patent family, one technical area); 1–2 weeks of supervised cutover. Production rollout is staged after the pilot meets your accuracy and SLA bar.

We benchmark against your current per-chart cost — typically $1,500–$5,000 at offshore patent ALSPs. Our target is 25–45% of that per-chart cost at higher accuracy and faster cycle time. Pricing structures around volume tiers and outcome SLAs, not hourly billable rates.
