A method, not a script.
- 01Understand the objective
What the client actually needs — not what a template complaint would ask for.
- 02Preserve the evidence
Documents, communications, and physical evidence are preserved, organized, and evaluated before the record becomes incomplete or disputed.
- 03Identify the leverage
Where the client has leverage—legally, commercially, and practically.
- 04Develop the strategy
A written plan for how the matter is resolved, with contingencies.
- 05Execute efficiently
Motion practice, negotiation, or trial preparation — whichever moves the matter.
Law, strategy, business, and human behavior.
Beyond the firm, Omeed publishes educational content on law and leverage, business and strategy, and ideas and human behavior. The work is separate from client representation, but the habits of mind are the same.

Recent writing.
California enacted AB 1609 on September 28, 2026, creating new rules for customer-service chatbots and access to human representatives at certain large private businesses. Despite shorthand descriptions of the law as a “15-minute customer-service rule,” the statute does not guarantee that every customer will speak to a human within 15 minutes. Instead, it establishes disclosure, human-access, and good-faith response requirements for businesses that meet the statute’s size threshold. AB 1609 takes effect January 1, 2027.
California enacted AB 2025 on September 27, 2026, creating new disclosure rules for AI-generated and digitally altered images used to advertise rental property. Beginning January 1, 2027, covered altered images generally must be clearly disclosed, and when an altered image was created from an actual photograph, the original image generally must also be made available. The law does not ban virtual staging or ordinary photo enhancement.
A California nonprofit filed suit against OpenAI Group PBC and OpenAI Foundation on September 29, 2026, seeking injunctive relief following a July cybersecurity incident involving OpenAI models and Hugging Face infrastructure. OpenAI and Hugging Face have both publicly acknowledged the underlying security incident, but the new lawsuit’s claims that OpenAI violated California law remain allegations that no court has adjudicated. The case also highlights a relatively new California rule addressing responsibility when artificial intelligence acts autonomously.
