<h1>Legal risks from company chairman's book and promotional press release: advertising, securities, defamation, IP and contract compliance</h1> A pharmaceutical company's chairman published and launched a leadership book via a commercial publisher, promoted at a public event featuring a prominent guest and distributed on e-commerce platforms. The press release asserts company financials, market leadership, product claims, awards, and public-health impact; it is presented under an agency arrangement with a disclaimer of editorial responsibility. Relevant legal considerations include compliance with advertising and consumer-protection laws for health and efficacy claims, securities and disclosure rules if statements influence investors, potential defamation or false-advertising risk from unverified assertions, and intellectual-property and publishing contract obligations.
