Patent Prosecution Lawyers Change Cities More Than Most: 2026 Data

Patent prosecution lateral hiring has a geographic feature that sets it apart: the lawyers are willing to move house as well as firm. Sartori & Partners data show that 30.2% of patent prosecution moves in the 12 months to October 2026 also involved a change of city, against 20.5% across all practices and 15.9% in intellectual property as a whole. For a firm building a prosecution bench, that widens the search well beyond its own city, and it changes what an offer has to cover.

The gap is wide for a measure that moves slowly. Patent prosecution sits 9.7 points above the market and 14.3 points above its own practice, where most moves stay inside one city. Life sciences and chemistry patent lawyers, the closest sibling speciality, changed city in 17.6% of moves, nearer the market than patent prosecution.

The longer view keeps the same shape. Over three years, 27.8% of patent prosecution moves changed city, against 21.6% in the market and 18.5% in intellectual property. One unusual year would not produce that consistency.

The reason sits in the work. Prosecution is practice before the patent office, not before a local court, and a prosecution docket can be run from any office with the right technical support. A prosecutor who joins a firm in another city gives up less local standing than a trial lawyer or a deal lawyer would, and the client relationship rarely depends on sharing a city.

For a hiring firm the consequence is practical. A search that covers only the home city leaves out many of the candidates who would accept the move. Relocation support, a transition period and a clear plan for the docket belong in the first conversation, not the last.

The second unusual feature is how often the lawyers arrive together. In the Sartori & Partners lateral database, 10.4% of patent prosecution moves came as part of a team, 6.9 times the market's 1.5%. Intellectual property as a whole recorded 5.1%.

Patent prosecution is not the most team-heavy corner of the patent field: life sciences and chemistry patent lawyers moved as teams in 13.7% of cases. What sets patent prosecution apart is the combination. Its lawyers move in teams far more often than the market, and they change cities more often than the practice, the sibling speciality or the market.

A prosecution docket is a portfolio of pending applications with fixed deadlines, worked by partners, associates, patent agents and technical specialists who know each file. When the partner who manages the portfolio leaves, the people who keep the deadlines often go too. Put together with the relocation figure, this means a firm can receive a working prosecution group in a city where it had no prosecution presence a quarter earlier.

The implication is to scope a patent prosecution search as a group from the start, with docket transfer, client consents and conflicts checked for the whole team before terms are discussed.

Over the last 12 months one city stands out. Boston took 16.6% of patent prosecution moves, an index of 641 against its weight in the whole market, where it took 2.6%. For intellectual property as a whole, Boston's index was 235.

Over three years the map is broader. Boston took 10.1% of patent prosecution moves and Washington, DC 10.0%, effectively level, followed by New York at 8.3% and Chicago at 7.4%. Washington, DC draws on the patent office nearby; Boston draws on the density of research-driven companies that file patents.

The life sciences and chemistry patent speciality shows an even stronger Boston pull, at an index of 826, so part of the Boston figure is patent work tied to the life sciences cluster there. A firm with a Boston office recruits where prosecution hiring is densest. A firm without one can still reach Boston candidates, because in this speciality a change of city is often part of the move.

Patent prosecution hiring leans toward the middle of the market. Firms of 400-999 lawyers took 35.0% of patent prosecution hires by firms of known size, against 23.4% across all practices and 24.2% in intellectual property. Firms of 1,000+ lawyers took 38.0%, well below the market's 53.6%, and firms of 150-399 lawyers took 22.7%, against 13.3%.

The three-year figures give the same answer: firms of 400-999 lawyers took 36.2% of patent prosecution hires, against 25.0% market-wide. Hiring is also concentrated. The ten most active hirers took 29.5% of individual hires, against 12.9% for the market's ten, and 80 firms hired at least one patent prosecution lawyer in the 12 months. Womble Bond Dickinson ranked first, in the 6-10 band of hires.

For a large firm, this is a market where mid-sized competitors carry more than their usual weight. A prosecution partner weighing offers will often hold one from a firm of 400-999 lawyers, so rate structure and the economics of volume prosecution work count as much as the size of the platform.

Volume did not follow the market. Sartori & Partners figures show that patent prosecution hiring held flat (-12.8%), with 163 moves in the 12 months to September 2026 against 187 a year earlier. Over the same windows, market-wide hiring rose 9.0% and intellectual property hiring held flat (+7.2%).

The level mix is part of the explanation. Partners made up 32.5% of patent prosecution moves and associates 38.7%, against 27.7% and 58.5% in the market. A flow weighted toward partners and counsel moves at the pace of individual careers and portfolios, and it does not swing with associate demand.

A steady count inside a rising market means the supply of patent prosecution candidates does not grow when hiring picks up elsewhere. Firms that need prosecution capacity compete for much the same number of movers each year, and the willingness to relocate is what widens the pool any one firm can reach.

Search nationally. With 30.2% of patent prosecution moves involving a change of city, a search confined to one city ignores many realistic candidates. Budget for relocation and a docket transition plan from the outset.

Plan for teams. 10.4% of moves came as teams, against 1.5% in the market. Map who works on a target partner's portfolio, check client consents and conflicts for the group, and price the whole team.

Expect mid-sized competition. Firms of 400-999 lawyers took 35.0% of hires, so a large firm's offer has to win on platform and economics against firms of that size.

Start in Boston, then widen. Boston's index of 641 makes it the deepest single source, and over three years Washington, DC matched it. With hiring that held flat (-12.8%), the pool will not grow on its own: the firm that reaches across cities reaches more of it.
