Patexia Insight 245: Trademark Shifts - Firms with the Largest Gains and Losses (2025)

The trademark legal market continues to shift, with law firms gaining or losing ground depending on client activity, industry trends, and broader market dynamics. Tracking year-over-year changes in filings provides valuable insight into which firms are expanding their presence and which are encountering challenges.

Drawing on data from Patexia’s 2025 Trademark Intelligence Report, we analyzed filing activity to identify the firms with the largest gains and the sharpest declines compared to the previous year. The findings reveal a competitive environment where some firms are on the rise, while others are seeing their position weaken.

Trademark Filing Trends (2020–2024)

Trademark filings reached their highest point in 2020 with more than 693,000 applications, before showing a slight dip in 2021. The market then experienced a sharp contraction in 2022, with filings falling to just over 551,000, the lowest level of the five-year period. Activity remained stable in 2023, hovering at a similar level, but 2024 showed a recovery, with filings climbing back close to 600,000. This pattern suggests a market that peaked early in the period, went through a significant correction, and is now showing signs of renewed momentum. Against this backdrop, certain law firms capitalized on the rebound and grew their share of filings, while others experienced declines. Below, we highlight the Top 5 Growing Firms and Top 5 Declining Firms in trademark filings, offering a snapshot of how the market is changing in 2025.

Kunzler Bean & Adamson continues to demonstrate growth, adding 4,981 filings over in 2024. While the increase is slightly lower than last year’s 6,334 additional filings, the firm maintains a strong and diversified client base. Analysis from our Trademark Analyzer confirms its continued presence in both national and international markets, with a notable share of filings still originating from Chinese companies. This ongoing engagement illustrates the firm’s sustained strategic focus on high-volume markets and its ability to maintain momentum following last year’s growth.

Brown Brothers Law, LLP ranks second in growth, adding 3,173 filings in 2024 compare to previous year. The firm also maintains a strong and diversified client base, with a notable proportion of filings originating from Chinese companies.

The Law Office of Timothy A. Duffy, P.C. ranks third in growth with 2,794 filings. Levy Law Associates (+2,458) and New Union Law, APC (+2,155) also show strong upward trends, highlighting their increasing activity and influence in the trademark space.

Several firms experienced a decline in trademark filings in 2024. Pasadena Legal Group saw the largest drop, with 4,710 fewer filings, followed by LZ Legal Services, LLC (-2,470), Michael Chen Law Offices, PLLC (-1,835), Mot Law Group, PLLC (-1,804), and RLAS (-1,559). These trends likely result from a combination of client base fluctuations, shifting market needs, and internal operational adjustments.

Looking at these patterns, it becomes clear that engagement with foreign clients can both drive expansion and expose firms to certain risks. This is particularly evident with Chinese clients: they benefit from the firms’ established expertise in trademark law, while the firms gain business growth, strengthened international portfolios, and an enhanced position in the global legal market. At the same time, reliance on foreign clients can introduce volatility, especially if there are shifts in international trademark filings. This highlights the importance of maintaining a diversified client base to ensure stability and sustainable growth.
