Better registered® trademarks™ instead of software patents

An addendum to software patents and a discussion with Dr. Paul Rübig on LinkedIn

Software is a composition of many individual components and different algorithms.

Prefer registered® trademark™ over software patents

Nevertheless, it is highly advisable to handle software patents with extreme cautio, as someone else may have already created this or a similar combination of identical algorithms, or someone else may create them without being aware of the patented work.

It is recommended to register complete products or product suites as registered trademarks ™ rather than  via software patents.
Registered trademarks offer better protection against virtually identical copies where only minor layout changes have been made and a code scrambler has been used.

Registered ® trademarks ™ prevent imitation of trademarks, but not of competing products, see

Code Snippets

In my opinion, code snippets, such as those used on Stack Overflow, Git, and in various API references, can be copied 1:1 into any source code if they atomic explanations, e.g.:

Basic statements, that are often used identically

Last but not least, 
limit patent (intelectual property) rights in time
Unlimited IP rights on patents would lead to monopols, which are dangerous for a developing innovative economy.
Pharma drugs have patent and Intelectual property right for some years, later generic pharma products are allowed to enter the market:
