Business proceedings in Dallas (Tex., USA) looking like a wrestling match

All began by the infringement of a French patent, the stake of it being trifling. The owner, a French company, decides to start an action against its French opponent, just to see. The assistant general manager of the company owning the patent, having some spare time, takes on the case. Then everything runs away. Suddenly that dispute, a trite case of infringement between two French companies, is increasing extensively due to the implication of the American mother company of the opponent : summoning in Dallas; entering the lists of a famous American consulting firm presenting steep accounts, removing the case from the Dallas Court to account of the Washington Federal Court, some tens million dollars being at stake. The action between the two French companies changes then into a wrestling match and tough negotiations ending in a long standing face to face, similar to a game of poker between the French assistant general manager and the American manager of the Texan mother company.
