E-commerce

Kronenberger Rosenfeld provides legal guidance for e‑commerce companies and consumer brands operating online. If you have a legal concern, contact our attorneys today.

E‑commerce and consumer brands live and grow online, but amplification often depends on aggressive advertising, performance and reputation marketing, influencer and affiliate relationships. The same strategies that drive sales and attention can create significant legal risk.

Kronenberger Rosenfeld is a leading California‑based law firm focused on internet, advertising, privacy, and e‑commerce law. We help online brands and retailers create compliant advertising campaigns and privacy policies, resolve disputes, respond quickly to business disparagement, and protect intellectual property. We have also defended online businesses facing high stakes FTC investigations, state attorney general inquiries, and private lawsuits tied to digital marketing practices.

Our clients include direct‑to‑consumer brands, subscription and continuity programs, online retailers, marketplaces, ad networks, affiliate programs, influencers, and other businesses whose revenue depends on how they operate online.

Who we serve

We work with a wide range of e‑commerce and brand‑focused businesses, including:

• E‑commerce and direct‑to‑consumer brands selling products online.
• Online retailers and subscription businesses using continuity and auto‑renewal models.
• Marketplaces, platforms, and app‑based sellers.
• Advertising networks, affiliate programs, and performance‑marketing agencies.
• Influencers, content creators, and brands that depend on paid social, email, SMS, and native advertising.
• Companies dealing with online defamation, fake reviews, and business disparagement.

How we help e‑commerce brands 

Advertising Law
Online brands face close scrutiny of their claims, disclosures, pricing, and marketing tactics. For over 25 years, Kronenberger Rosenfeld's advertising law practice has focused on digital media, providing advice on compliance with FTC rules and state consumer‑protection laws, and defending clients facing investigations and lawsuits.

SMS programs, retargeting, lead generation funnels, email and social media campaigns, and affiliate traffic can all trigger allegations that a brand’s outreach violated federal or state marketing laws, including the FTC Act, the Telephone Consumer Protection Act (TCPA), and CAN‑SPAM. We review advertising content, funnels, campaigns, and subscription and billing flows to identify and reduce legal risk. When necessary, we defend e‑commerce clients in false‑advertising, deceptive marketing (including Made in USA claims), and consumer‑protection class actions.

Intellectual Property and Branded Content
For e‑commerce and consumer brands, trademarks, logos, product names, packaging, creatives, and content are core business assets. We help brands secure and enforce trademarks and copyrights for products and digital content, develop strategies to protect trade secrets and proprietary information, and act against infringement, counterfeit goods, knock‑off listings, and unauthorized sellers. When necessary, we litigate copyright and trademark disputes involving websites, digital products, and online advertisements.

Privacy, Terms, and Website compliance
E‑commerce brands rely heavily on data collection, tracking, and personalized marketing. Our privacy policy attorneys have significant experience in navigating CCPA, GDPR, TCPA, CIPA, and related rules. We review and draft privacy policies, terms of use, return and subscription policies, consent flows, and data‑use practices so brands can better align with privacy and consumer‑protection expectations. We also represent clients in privacy and data‑related disputes, helping brands respond to consumer complaints, investigations, and claims tied to their online practices.

Advertiser and affiliate agreements
Performance marketing is central to many e‑commerce brands, but lacking advertiser and affiliate agreements can turn routine tracking or payment disputes into high‑stakes litigation. Our goal is to keep programs profitable and compliant while reducing the chances that disagreements escalate into disruptive lawsuits, proactively addressing real‑world issues like fraud, misleading claims, spam exposure, and regulatory investigations.

We draft and revise advertiser, affiliate, and network agreements to reflect practical risk allocation and program rules, and we represent clients in disputes with affiliates, networks, merchants, and regulators.

Domain Disputes
Domain names, URLs, and platform handles are part of a modern brand’s identity. Kronenberger Rosenfeld often handles cybersquatting litigation, UDRP proceedings, domain‑theft and digital‑asset disputes, and other domain‑name and platform‑related conflicts.

We help brands secure and protect critical domains, resolve disputes through arbitration or litigation, and address impersonation, hijacking, or brand‑abuse issues that can disrupt traffic and sales. These conflicts can unfold quickly, so we focus on rapid, practical responses that protect business continuity.

Click Fraud 
When bots, competitors, or bad‑faith publishers generate fake clicks with no intention of buying, they exhaust budgets, distort campaign data, and make it harder for real customers to see your ads. We help clients spot red flags and investigate suspicious activity and pursue legal remedies under federal and state law for unauthorized or fraudulent activity.

Online Defamation and Business Disparagement
A single defamatory website, fake review, or smear campaign can quickly appear at the top of search results and materially impact an e‑commerce business. Our team battles business disparagement by using federal and state laws to vindicate commercial clients harmed by online defamation, including damaging content posted by former employees, fake reviews from competitors, or unfair ratings from disgruntled customers.

We work to identify anonymous bad actors, obtain removal of defamatory content from websites and search engines, and pursue litigation where necessary to recover damages and deter ongoing attacks.
