To expedite resolution and control the cost of any dispute, controversy, or claim related to these Legal Terms (each a "Dispute"), the Parties agree to first attempt to negotiate any Dispute (except those expressly provided below) informally for at least thirty (30) days before initiating arbitration.

The seat of arbitration shall be Lund, Sweden. The language of the proceedings shall be English. Applicable rules of substantive law shall be the law of Sweden.
The Parties agree that any arbitration shall be limited to the Dispute between the Parties individually. To the full extent permitted by law, (a) no arbitration shall be joined with any other proceeding; (b) there is no right or authority for any Dispute to be arbitrated on a class-action basis or to utilize class action procedures; and (c) there is no right or authority for any Dispute to be brought in a purported representative capacity on behalf of the general public or any other persons.
The Parties agree that the following Disputes are not subject to the above provisions concerning informal negotiations and binding arbitration: (a) any Disputes seeking to enforce or protect, or concerning the validity of, any intellectual property rights of a Party; (b) any Dispute related to, or arising from, allegations of theft, piracy, invasion of privacy, or unauthorized use; and (c) any claim for injunctive relief.
