Entire guerrilla wars are unfolding in the field of intellectual law. Owners of patents for inventions, developers of know-how, authors of works, managers of companies with successful brands and trademarks strive to obtain a monopoly on their rights and extract maximum profit from them. Competitors are not asleep, trying to “grab a piece of the pie.” The methods used are very different: from relatively honest to illegal. The author does not hide either one or the other, because the strongest will win. Tactics and strategy for victory in this war, taking into account the specifics of various branches of activity, are the basis of the book.
