这两个词组中“shop”的意思完全不同。

shop right是专利法中的术语，指雇员发明实施权。

具体而言，shop right指雇主可以在其业务中免费使用雇员的发明的权利。它实际上是雇主以法律推定的方式从其雇员处得到的一种非独占性专利实施许可，当某一雇员并非专门受雇从事发明工作，但其在工作中运用雇主的设备完成发明的，则通常可以在法律上产生一种雇主对雇员发明的实施权。其英文释义如下，供参考：

Shop right, in United States patent law, is an implied license under which a firm may use a patented invention, invented by an employee who was working within the scope of their employment, using the firms' equipment, or inventing at the firms' expense. Even if the employee never assigned rights to the firm, a court of law may find that the firm has the right to make use of the invention, and thus can not be sued by the employee for patent infringement. This will allow the firm to attempt to capitalize on the value of the patent, as the firm is allowed to use the object of the patent in the routine operation of its business without royalty payments. Shop right is non-transferable. It only inures to the benefit of the employer and can not be sold by that employer to an unrelated party, except in a sale of the business as a whole.

与之相对应的原则是：shop right rule雇员发明实施权原则

根据该原则，雇主有权免费使用雇员所完成的发明。但雇主所获得的专利实施许可是非独占性的，并且不能转让他人。对雇员发明的实施权是基于雇主对该发明的完成所付出的材料、时间和设备。

而no-shop clause则指的是并购交易中的不招揽承诺，也叫non-solicitation。

不招揽承诺是指目标公司董事会向买方做出的在签约后到交割前不主动招揽其他竞争性投标的承诺。不招揽承诺能确保目标公司董事会只能被动地接收竞争性投标，买方至少能在一定程度上控制目标公司可以考虑和接受的竞争性投标的类型。不招揽承诺主要包括几方面义务：

禁止目标公司董事会及其代表招揽或鼓励竞争性投标；

禁止目标公司董事会及其代表向第三方提供信息或与第三方进行谈判；

要求目标公司董事会在收到未经招揽的竞争性投标时通知买方。

与之对应的条款是go shop，意即目标公司董事会可以在签约后主动去市场上进行询价，此类条款一般只有在目标公司董事会没有进行或没有有效的进行签约前市场询价的交易中才可能为买方所接受；即便如此，买方可能会同时要求其他交易保护条款，比如相对高额的分手费。

其相关英文释义如下，供参考：

A no-shop clause is a clause found in an agreement between a seller and a potential buyer that bars the seller from soliciting a purchase proposal from any other party. In other words, the seller cannot shop the business or asset around once a letter of intent or agreement in principle is entered into between the seller and the potential buyer. The letter of intent outlines one party's commitment to do business and/or execute a deal with another.
