Common Types of Business Disputes

At Oberheiden P.C., we have counseled businesses involved in many types of disputes and claims. No matter your industry, our legal team can help. We can represent your business in the following legal disputes.

Antitrust and Securities Litigation

Antitrust and securities violations are some of the most complex issues within the business world. These high-stakes matters should only be left to a skilled litigation attorney. When you need a law firm to defend your company against antitrust or securities accusations, the legal team at Oberheiden P.C. has extensive experience working with these complicated cases. We have successfully defended our clients against securities and antitrust claims all across New York and the United States.

Breach of Contract Actions

When anyone signs a contract, it is a legally binding agreement to adhere to specific stipulated terms. If one party does not live up to those agreements and expectations, it could be time to take legal action. Breach of contract actions are relatively common, often stemming from unclear expectations and terms listed in the contract. Whether you need to enforce an agreement or have a breach of contract accusation levied against your business, Oberheiden P.C. can assist you. With help from our experienced business litigation attorneys, we will examine all the contract terms to determine what is enforceable. Not all contracts are the same, and our team will take an individualized approach to these legal issues.

Business Fraud

Any accusation of business fraud is serious and must be handled with only skilled legal counsel. In some situations, business owners and executives could be personally liable for monetary losses. If you are under investigation for fraud or there has been an allegation against your company, reach out to us. At Oberheiden P.C., we have helped defend many businesses against these types of accusations. Over the years, our law firm has successfully defended clients against these claims in various industries, including healthcare, insurance, securities, accounting, and banking.

Employment Litigation

In many cases, businesses can understand the issues involved in typical business disputes, but employment litigation is often more complex. With these claims, you need the assistance of an experienced employment litigation lawyer who understands these legal issues. From the enforcement of a non-compete agreement to an allegation of stolen property, our litigation attorneys at Oberheiden P.C. will develop a comprehensive strategy to protect your business and limit any legal liabilities.

Shareholder, Partner, and Member Disputes

When business partners or shareholders cannot agree on the direction of their company, it can lead to complicated disputes. Many times, we can find mutual ground to help resolve these issues. At Oberheiden P.C., our attorneys have extensive experience working with shareholders, partners, directors, and other members of the organization to come up with a solution that meets everyone’s needs and interests.

Infringement and Misappropriation of Intellectual Property

At Oberheiden P.C., we consider intellectual property to be one of your business’s most important assets. When there are issues with patents, copyrights, or trade secrets, our legal team is ready to help navigate through these complex legal issues and protect your business from losing those valuable assets.

Tortious Interference

If a third party has intervened in a contract or a relationship that you have with a business partner, your company can suffer losses that can give it grounds for a legal claim. That legal claim is referred to as tortious interference. These cases need to be investigated to uncover evidence or validate an allegation of interference. At Oberheiden P.C., our senior litigation attorneys have worked as former federal officials and investigators. Many of them have previously handled these types of cases. They will take their time to investigate these claims made against your business.

Mergers and Acquisitions

Every year, there are thousands of acquisitions and mergers. These mergers have high stakes, with many complicated issues surrounding the transfer of ownership and other legal matters. At Oberheiden P.C., we have a team of attorneys who have successfully navigated any problem that can occur with these deals. Our legal team will try to keep the case out of the court system by working to negotiate a settlement or resolve any issue. However, if we need to head to court, we will prepare for trial to protect your interests.

Frequently Asked Questions About Business Litigation

Is Litigation Always Necessary?


Litigation should not be seen as a last resort. It is an important tool in today’s business world. Companies often need to pursue litigation for a wide range of circumstances. They may need to protect their intellectual property or enforce contract terms. While there are alternatives to litigation, hiring an experienced law firm can be enough to trigger the other party to act in good faith and resolve the dispute.

When it comes to litigation, it can also play a role in compliance efforts. For example, if a third party provides a non-compliant service, it can mean losses for your business. You can pursue litigation to help recoup any financial damages your business experienced. Also, litigation may help protect the business’s assets in the event of a federal compliance investigation.

How Do You Respond To a Business Lawsuit?


The clock starts to tick if someone has filed a lawsuit against your business. In many cases, you will need to file a response to the complaint. The response deadline can vary depending on the jurisdiction. Once the defendant has been served, they need to find the proper counsel to evaluate their options and determine an appropriate strategy for their defense. Often, the plaintiff can also serve a discovery request, meaning the defendant will have to respond to that issue. The defendant needs to hire an experienced legal team to handle these matters. By taking a proactive approach, you can build a solid defense to resolve these cases.

What Are a Few Outcomes of Business Litigation?


The vast majority of business litigation cases end up getting dismissed by the court or settle outside of the courtroom. Those settlements can include monetary damages, injunctive relief, or a mixture of the two. If no settlement is reached, the case will go to trial and the judge or jury will impose a resolution in the form of a verdict. If any party is dissatisfied with the outcome, they can pursue additional litigation in the appeals process.

How Do You Initiate a Business Lawsuit?


The process of initiating a business lawsuit is more complex than drafting and sending a complaint. Before any legal action is taken, the company’s leaders will work with their legal team to assess the litigation’s costs, benefits, and risks. Sometimes, they may want to seek an alternative path to litigation. Any business contemplating litigation should plan its strategies before filing the lawsuit in a state or federal court. Also, they must anticipate any potential issues that could arise with a lawsuit. The defendant may be able to file a counterclaim that can expose the business to other liabilities. Knowing what to expect in these cases is crucial. At Oberheiden P.C., we have the experience to know what to expect. Our legal team can offer advice on whether you should file a lawsuit or seek other alternatives to resolve your business dispute.
