Antitrust FAQ

What Is Antitrust?

Antitrust law is designed to protect and maintain competition for a product or service. When there is competition for business, companies must update and innovate new products on an ongoing basis to attract customers. They cannot charge exorbitant prices, because if they do, the customers will simply go to one of their competitors to buy the product or service for less money. Business practices that reduce competition illegally, therefore, throw the system out of whack. Consumers no longer get the best product or service for the best price. This is what the antitrust laws are designed to protect against.

What is Unfair Competition?

Unfair competition is defined broadly as business conduct that is “contrary to honest practice in industrial or commercial matters.” The types of conduct that fall within this definition are things such as trademark infringement, false advertising, misappropriation and what is referred to as “palming off.” A company is guilt of “palming off” when it makes representations or designs or packages its product in such a way as to confuse buyers as to which company’s product they are purchasing. The buyer purchases the product thinking it is one thing, only to find out later that they were deceived into purchasing counterfeit.

What Makes Certain Practices Anti-Competitive or Illegal?

A practice is anti-competitive or illegal if a company uses its market power to reduce or eliminate competition in the market, or to reduce or eliminate competition in a secondary market in which it does not have such power. A good example is computers and printers. Today you can purchase a computer from one company and a printer from another. Say that I make such great computers that 80% of buyers buy my computer, but my printers are not terribly good and do not fare well when in competition with other manufacturers’ printers. If I use my market power in the market for computers to force customers to buy my printer too, when they would normally purchase the printer elsewhere if given the choice, that is an example of an anti-competitive practice.

How Do You Prove That a Practice is Illegal?

Certain practices, such as price fixing, are so clearly harmful to competition that little more is needed than proof of the agreement to fix prices itself. If all of the competitors in a market agree to charge the same price, then there can never be any price competition. Most practices, however, require a more detailed analysis that always involves two questions: (1) What is the relevant market?; and (2) Does the defendant have “market power” in that market. The bigger and more powerful the company, the more likely its conduct can affect competition in the market. The more narrowly the market is defined, the more likely that company’s business practice will be found to harm competition. A rock dropped into a glass of water, in other words, is going to have a much greater impact on the water in that glass of water than if I were to drop the same rock into the Pacific Ocean.

I have known Brian Weinberger for many years. As a fellow lawyer, I can highly recommend him. He cares about his clients and gets great results in mediation and litigation. He provides the needed comfort and hand holding for the people he represents during the stressful times in litigation or meditation. He also settles many case when it is for the client’s advantage. He will not waste your money. If a matter does not make financial sense, he will explain to you why you should not spend any monies on the matter. He will use the legal tools that will benefit you the most. He has tireless energy and has gifted skills and knowledge to get you the best results. You will always have a great lawyer and friend in your corner. Quite frankly, I would pick Brian as my own attorney, if I needed one.

Our company retain Weinberger Law Firm to represent us in a contractual disagreement with a former employee. Brian's (and his team's) meticulous attention to detail, knowledge of the law and commanding presence in Federal District Court assured a positive result for our company that was upheld upon appeal to the 9th Circuit Court of Appeals (San Francisco). It is without hesitation that I recommend Weinberger Law Firm for commercial contract litigation.

I have needed Mr. Weinbergers' assistance on a few occasions. He was incredibly fast, insanely knowledgeable and had what I found to be great pricing. I really can't stress how great it was to work with him. He was very friendly and treated me like family. He will sit down and really make sure you understand every step of the process, which is very helpful when an average joe like myself needs to understand what anyone is talking about regarding laws. Thanks!
