IP Partner Track by US City: Boston Runs Fastest, New York Slowest

The intellectual property partner track by city splits into two speeds. Sartori & Partners data show that 42.3% of the IP lawyers promoted to partner in Boston over the last 5 years got there within 8 years of their first year of practice, against 16.5% in New York. Across every market we track, the IP figure is 25.1%, so Boston runs well ahead of the practice and New York well behind it. New York and Washington, DC hold the two largest IP benches, with 143 and 110 IP lateral moves in the 12 months to October 2026, and neither reaches the practice-wide share. The quick clocks sit in mid-sized benches: Boston, Dallas and Chicago. The figures come from public law-firm announcements, firm websites and professional profiles, checked monthly. Time to partner counts the years from the first year of practice to the promotion, the city is where the partner practices today, and each city figure covers the partners promoted there over the 5 years to May 2026.

The gap runs through the whole distribution, not only the front of it. The median Boston IP partner was promoted after 9.0 years, against 11.0 years in New York. The quickest quarter of Boston promotions came by 7.0 years, New York's by 9.0 years, and the upper quartile sits at 11.0 years against 12.0 years. Within 12 years the spread narrows to 84.6% against 77.4%: most New York IP associates who make partner still get there, only later.

Each city also departs from its own market. Boston lawyers in all practices made partner within 8 years 22.8% of the time, so IP in Boston runs 19.5 points ahead of its city. In New York the all-practice figure is 20.3%, and IP trails it by 3.8 points. The Boston reading rests on 52 promotions with a known first year of practice, New York's on 133. The smaller base makes the Boston share a rough size; the direction is the part to plan on.

For a firm recruiting a senior IP associate, the city sets the clock. A Boston associate at 9.0 years of practice has reached the usual promotion point. A New York associate at the same stage is still 2 years short of the local median, and a lateral offer has to price that wait.

Boston is not alone. In Dallas, 33.3% of IP partners promoted over 5 years made it within 8 years, with a median of 9.0 years and an upper quartile of 10.0 years, the shortest of the eight cities. Dallas lawyers across all practices made partner within 8 years 18.7% of the time, so IP runs 14.6 points ahead of its own city. The Dallas base is small, 33 promotions, so read the share as a size, not a ranking.

Chicago shows its speed further out, at the later cut-off. Sartori & Partners promotion records put 87.0% of Chicago IP partners within 12 years, the highest share among these cities and above the all-market IP figure of 78.6%. Within 8 years Chicago reaches 31.9%, on a median of 9.0 years. Chicago is a quick city in general, with 84.8% of its partners in all practices promoted within 12 years, so IP there moves with its market rather than ahead of it.

Atlanta sits between the two groups. Its IP partners made it within 8 years 25.8% of the time, on 31 promotions, close to the practice-wide 25.1%.

In these cities the quicker clock is a retention fact. An IP associate in Dallas or Chicago expects a decision near 9.0 years of practice. A firm there that holds the decision back to a New York timetable gives its own associates a reason to listen to local competitors.

Size does not buy speed. New York, Washington, DC, San Francisco and Los Angeles are the four largest US IP benches by lateral moves, and each sits below the all-market IP share of 25.1% within 8 years. Los Angeles reached 18.5%, San Francisco 19.4% and Washington, DC 21.4%. All three share a median of 10.0 years, against 9.0 years in Boston.

Washington is slow against the practice but quick against its own city. DC lawyers in all practices made partner within 8 years 14.4% of the time, so IP there runs 7.0 points ahead of the DC market. San Francisco follows the same pattern, at 19.4% for IP against 15.6% for the city. In Los Angeles the two readings nearly match, 18.5% for IP and 18.3% for all practices.

For a firm hiring into these benches, the long clock is a sourcing advantage. More senior IP associates sit past the local median with no decision yet, and the benches are deep: 98 IP lateral moves joined San Francisco and 69 joined Los Angeles in 12 months.

Speed and volume point in different directions. From June 2025 to May 2026, firms promoted 31 IP lawyers to partner in New York and 21 in Washington, DC, the only two cities where the 12-month IP count is large enough to publish. New York alone accounts for 13.2% of the 234 IP promotions recorded across all markets. Over 5 years the two cities count 141 and 108 IP promotions, against 56 in Boston and 34 in Dallas.

In the Sartori & Partners lateral database, the practice as a whole promoted 0.65 IP lawyers for each lateral partner it hired, against 0.79 across all practices. IP partnerships in every city lean on lateral hires, and New York and Washington, the two largest benches, also see the most IP lateral moves.

The volume sits where the clock is slowest. A firm that needs several IP partners in a year will find most promotion-ready candidates in New York and Washington. A firm that wants partners earlier in their careers should look at Boston, Dallas and Chicago, where fewer are made but they are made sooner.

The two quickest cities do different work. Over 3 years, patent prosecution figured in 37.1% of Boston IP lateral moves and life sciences patents in 31.1%. Dallas leans the other way: patent litigation figured in 48.3% of its IP moves and trade secrets in 36.0%. Washington, DC is just as litigation-heavy, with patent litigation in 49.5% of its IP moves, and yet its clock runs slower than the practice. New York leans on patent litigation at 32.8%, copyright at 26.0% and trademarks at 25.3%.

A litigation-heavy IP bench can therefore run quick, as in Dallas at 33.3% within 8 years, or slow, as in Washington at 21.4%. These are shares of lateral moves, and one lawyer can carry several specialities, so they describe each bench rather than rank them. The practical point: judge a candidate's promotion prospects by the city and the firm, not by the specialty label alone.

Set promotion expectations city by city. A firm with IP groups in Boston and New York runs two different clocks: 42.3% of Boston IP partners against 16.5% of New York's arrived within 8 years. A single firm-wide timetable will feel slow in Boston and quick in New York, and Boston associates will measure it against their own local market.

Recruit senior associates from the slow benches. New York, Los Angeles and San Francisco hold associates past the local median who have not yet been promoted, and a firm in Boston, Dallas or Chicago can offer a partner decision on a shorter clock. Sartori & Partners data put the Los Angeles IP figure at 18.5% within 8 years, so a credible early decision is a real offer there.

Plan lateral partners for volume. With 31 IP promotions in New York and 21 in Washington in 12 months, homegrown supply in the two largest benches is real but slow. A firm that needs IP partners this year will buy most of them, and should budget the search before the promotion round, not after it.
