It is a meaningful grouping of disputes that is nonetheless amorphous and somewhat dependent on the eye or experience of the beholder.  One clear portion involves, at bottom, a business contract or relationship of one type or another.  My experience has included claims and allegations, often relatively complex but some more routine or common, concerning:

• Contracts or deals for services, products, equipment, assets, facilities, commissions, guarantees, leases
• Securities fraud or misstatements in sales of securities or financial statements
• Fiduciary duties of directors, officers, partners and employees in corporations or partnerships; shareholder derivative claims; corporate governance provisions
• Accountants' liabilities
• Lawyers' liabilities
• Class action defense in a variety of substantive areas, including securities laws, equal employment opportunity laws, consumer fraud, product liability and federal and state taxation
• Employment contracts
• Covenants not to compete, in asset sale and in employment-only contexts
• Race, sex, age and national origin discrimination
• Regulation of public utilities, telephone, electric, railroad (freight and commuter)
• Product liability
• Commercial fraud and other business torts such as unfair competition, protection of trade names or secrets, tortious interference
• Defamation of public figures or on matters of public interest
• Various constitutional issues, such as Commerce Clause, 21st Amendment, and Free Speech and Press
• Administrative law and regulation
• Appellate practice
