Feedback across 24 reviews is mixed, producing an average rating of 3.6. Positive reviews point to the firm’s long-standing reputation in the field, creative thinking, and general service quality. Reviewers describing themselves as smaller clients tell a different story: repeated complaints center on unreturned emails and phone calls, slow or old-school communication, and billing that exceeds initial estimates without advance notice. One reviewer reported charges for quoting a price, negotiation calls, and internal communication; another described invoices far above what was quoted. These accounts suggest a firm whose depth and technical reach are widely acknowledged but whose responsiveness and cost predictability are uneven, particularly for smaller or startup clients.

The Irvine office can be reached at 949-760-0404, and the firm publishes news, blogs, and litigation updates through its website. Prospective clients weighing the firm may want to clarify engagement terms, billing practices, and communication expectations before proceeding, and to consider whether its scale matches the size and budget of their matter.
