Business law in Germany, also known as commercial law, governs the legal relationships and transactions between businesses and individuals in Germany. It is a complex and diverse field that covers a wide range of areas, including contract law, corporate law, intellectual property law, and competition law.

One of the key areas of business law in Germany is contract law. According to the German legal scholar Ulrich Drobnig, "Contract law in Germany is based on the principle of freedom of contract, which means that parties to a contract are free to agree on its content and terms." (Drobnig, U. (2008). Principles of German Contract Law. Cambridge University Press) This principle is reflected in the German Civil Code (Bürgerliches Gesetzbuch, BGB), which regulates the formation, content, and termination of contracts in Germany.

Another important area of business law in Germany is corporate law. According to the German legal scholar Joachim Römer, "Corporate law in Germany is governed by the German Stock Corporation Act (Aktiengesetz, AktG) and the German Transformation Act (Umwandlungsgesetz, UmwG)." (Römer, J. (2018). Corporate Law in Germany. C.H. Beck) These laws regulate the formation, management, and dissolution of companies in Germany, including public companies and private limited liability companies (Gesellschaft mit beschränkter Haftung, GmbH).

Intellectual property law is also an important area of business law in Germany. According to the German scholar Rainer Enskat, "Intellectual property law in Germany is governed by the German Copyright Act (Urheberrechtsgesetz, UrhG), the German Patent Act (Patentgesetz, PatG), and the German Trade Mark Act (Markengesetz, MarkenG)." (Enskat, R. (2015). Intellectual Property Law in Germany. C.H. Beck) These laws protect the rights of authors, inventors, and trademark holders in Germany.

Competition law is another important area of business law in Germany. According to the German legal scholar Alexander Giegerich, "Competition law in Germany is governed by the German Act Against Restraints of Competition (Gesetz gegen Wettbewerbsbeschränkungen, GWB) and the German Regulation of Unfair Competition (Gesetz gegen den unlauteren Wettbewerb, UWG)." (Giegerich, A. (2016). Competition Law in Germany. C.H. Beck) These laws prohibit anti-competitive practices, such as cartel formation and abuse of a dominant market position.

In conclusion, Business law in Germany is a complex and diverse field that governs the legal relationships and transactions between businesses and individuals in Germany. It covers a wide range of areas including contract law, corporate law, intellectual property law and competition law. These laws are governed by different acts and regulations that are designed to protect the rights of businesses and individuals, and to promote fair competition in the German market.
