Jeffer Mangels Butler & Mitchell LLP Announces Formation of Trademark Trial and Appeal Board Group

LOS ANGELES—Jeffer Mangels Butler & Mitchell LLP (JMBM) has announced the formation of its Trademark Trial and Appeal Board (TTAB) Group, which handles cases involving trademark disputes, oppositions, cancellations, and appeals before the United States Patent and Trademark Office’s (USPTO) Trademark Trial and Appeal Board.

Comprised of seasoned Intellectual Property attorneys with a combined 40 years of experience in TTAB proceedings, JMBM’s TTAB Group has a proven track record of success representing clients throughout the dispute resolution process.  JMBM partners Rod Berman and Jessica Bromall Sparkman will lead the group as Co-Chairs.

The Group counsels clients in a wide range of matters including:

  • Bringing and defending against petitions to cancel
  • Notices of oppositions
  • Section 18 proceedings
  • Both inter partes and ex partes appeals

“The formation of JMBM’s TTAB Group underscores the firm’s commitment to safeguarding clients’ trademark rights,” said Berman. “Our attorneys have decades of experience delivering favorable results domestically and abroad across every industry, including wellness and medical devices, luxury goods, and food, drink, and tobacco. Whether it’s securing wins after full trials, obtaining summary judgments, or establishing crucial defenses, we are dedicated to providing top-tier legal counsel.”

JMBM’s TTAB Group has prevailed at summary judgment, taken testimony, presented evidence by declaration as well as Notice of Reliance, and taken cases through trial and oral argument before the Board. This extensive experience sets JMBM’s practice apart from those that rely solely on procedural filings.
