In this era, it is almost impossible to file cross-border patent lawsuits, especially when the cooperating parties are all these powerful nations.
Even if you could win a patent lawsuit, by the time you do, electrical technology would have already undergone several iterations.
For this reason, in any patent-related cooperation, Spain insists on directly selling patents. Carlo doesn't trust the moral character of other countries; patent infringement is almost everywhere during this era, and no one would be foolish enough to comply with so-called patent clauses.
Selling patent technology is still quite profitable. Just from selling patent technology to the United States and France, the Spanish National Power Company received returns exceeding 20 million Pesseta.
In addition to the revenue from selling power generation equipment and electric lamps, Carlo has fully recouped all the costs invested in the Electricity Laboratory, and even made a small profit.
