Jeff represents clients in intellectual property litigation and Internet-related litigation, handling the wide variety of legal issues that arise in connection with the Internet. In particular, Jeff’s practice focuses on the following types of cases:

  • Copyright and Trademark Infringement: Jeff regularly represents both defendants and plaintiffs in copyright and trademark infringement lawsuits involving website content, digital products, and online advertisements.
  • Online Defamation: Jeff has extensive experience representing both plaintiffs and defendants in defamation cases involving online content. Jeff has litigated all aspects of online defamation matters from anti-SLAPP through trial, and he has worked with clients and experts to quantify both economic and non-economic damages in such cases.
  • Spam, TCPA, and Telemarketing Defense: Jeff devotes a significant portion of his practice to defending spam, TCPA, and telemarketing litigation, and he has been involved in several precedent-setting cases. Jeff is well-versed in all aspects of the relevant spam and TCPA authority as well as the practical trial and settlement dynamics of spam and TCPA litigation.
  • False Advertising on the Internet: Jeff’s clients are primarily online retailers of everyday products and services, such as dietary supplements, office supplies, home electronics, and car rental services. Jeff represents these clients when their competitors make false statements in advertisements, or when Jeff’s clients are accused of making false statements about their own products and services.

In addition to his litigation practice, Jeff counsels clients on strategic Internet-related issues, including compliance with FTC regulations in online marketplaces, advising on the design and operation of e-commerce websites and the disclosures made on those websites.

“We use a practical approach to all of our litigation. We take into consideration our client’s goals, all of the possible outcomes, and the realistic cost of the litigation in order to develop a vigorous strategy to achieve our client’s goals.”

  • Represented a major Internet advertising network in an $11 million federal spam lawsuit by a professional spam plaintiff. Prevailed on behalf of client at summary judgment on all claims in the lawsuit; obtained order awarding over $806,000 in fees and sanctions against the professional spam plaintiff.
  • Prevailed on motion to dismiss on behalf of multiple defendants named in a $400 million spam lawsuit brought by a major Washington, D.C. law firm.
  • Represented the owners of a popular online dating website against a professional spam plaintiff in a $19 million California spam lawsuit. Obtained a full dismissal with prejudice for one of the firm’s clients at summary judgment and resolved the remainder of the case shortly thereafter.
  • Represented an online retailer of printer supplies in a trademark infringement lawsuit brought by a billion dollar printer manufacturer.
  • Successfully defended a web development company in a federal trademark lawsuit. After a five-day jury trial, the client defeated all of the plaintiff’s claims, with the jury finding that the plaintiff had not established any valid trademark rights.
  • Represented an online merchant in numerous copyright infringement cases where competitors had copied and displayed the client’s product images on the infringers’ own websites. In each case, the firm reached a favorable settlement on behalf of the client.
  • Represented a large online merchant in a lawsuit against a payment processor and payment gateway, which alleged that the defendants had skimmed small amounts from each of the client’s online transactions resulting in a total theft of more than $1.6 million. After extensive discovery and motion practice, the parties settled in favor of our client.
  • Represented the plaintiff in a federal lawsuit against a large online merchant based on the merchant’s creation and settling of financial instruments without proper authorization. The suit was one of the first to address the federal Restore Online Shoppers’ Confidence Act (ROSCA), and helped define the contours of this important law. The firm ultimately reached a settlement with the defendants in favor of the client.
