BD for Patent Prosecution Practices: Signals, Cadence, Outreach

Patent prosecution is the practice where bad BD does the most damage. The work is recurring, the margins are tight, and the buyer is sensitive to noise. A clumsy outreach to an in-house patent counsel does not just fail to convert — it actively poisons the relationship for the partners who might have earned the introduction the right way. Patent prosecution BD rewards relevance over volume.

What the buyer actually wants

In-house patent counsel are inundated. They receive cold pitches every week, most of which are interchangeable, and they have learned to ignore them. What they respond to is specific, timely, and substantively useful contact. A note that references a specific family they are prosecuting, a specific examiner pattern in a specific art unit, or a specific jurisdictional issue they are about to encounter will be read. Everything else will not.

This means that the unit of BD work in patent prosecution is not the campaign. It is the individual, well-researched touch. Volume thinking destroys the practice. Relevance scales it.

Signal triage

The signals are abundant. Published applications at the EPO, USPTO, JPO, KIPO, and CNIPA, PCT filings at WIPO, family extensions, validations, oppositions, examiner reports, continuation filings, divisional filings, and post-grant proceedings all produce structured data. The problem is not finding signals. The problem is triaging them.

A useful triage model has three tiers. Tier one is account-specific motion — an existing client or named prospect filing in a new jurisdiction, transferring representation, or entering a new technical area. Tier two is technical-area motion — a sector the firm specialises in showing a surge in filings, oppositions, or post-grant proceedings. Tier three is broader market motion — useful as context for thought leadership but not as a trigger for direct outreach.

Lexi handles the triage by reading the registers continuously, scoring filings against the firm's accounts and practice areas, and pushing the tier-one signals to the responsible partner with the context they need. She does not draft the prosecution strategy. She makes sure the partner knows, within hours, that a target account has just filed a divisional in a jurisdiction where the firm has a strong story.

Account cadence

Cadence in patent prosecution is a matter of judgement, not arithmetic. A mid-sized in-house team might be comfortable with quarterly substantive contact and event-driven touches in between. A large in-house team with established panel arrangements might tolerate less direct contact but more conference presence and written commentary. A small in-house team or a fast-growing scaleup might welcome more frequent contact, particularly if it is structured around their actual filing rhythm.

The mistake to avoid is imposing a uniform cadence across all accounts. The firms that get this right segment the account base by maturity, panel structure, and filing volume, and run a different cadence for each segment.

Outreach that earns a reply

A reply rate of ten percent on patent prosecution outreach is excellent. A reply rate of one percent is normal. The difference is almost entirely in the first two sentences. An outreach note that opens with a specific, demonstrably researched observation about the recipient's portfolio will outperform one that opens with a generic claim about the firm.

The structure that works is short. One sentence of specific context. One sentence of substantive observation. One sentence proposing a low-friction next step. No attachments, no firm brochure, no marketing copy. The buyer's time budget for an unsolicited message is measured in seconds.

What gets reported up

A practice group leader running a serious patent prosecution BD operation should be able to answer four questions every month. Which accounts have shown motion that warrants attention. Which partners have made contact and with what response. Which signals were missed or surfaced too late. And which conversion paths are progressing through defined stages toward a mandate.

These are operational questions. They require continuous data, not a quarterly spreadsheet exercise. Lexi maintains the underlying picture so the practice group leader can run the review in twenty minutes rather than two days.

The discipline that matters most

The discipline that separates effective patent prosecution BD from busy patent prosecution BD is restraint. The temptation to push volume is constant. The buyers do not respond to volume. They respond to a partner who knows their portfolio, understands their pressures, and shows up at the right moment with the right observation. Build the operation around that, and the practice grows.
