can a student who majored in philosophy become patent lawyer?

I dont see why not, since law schools never claimed that they only want students with specific majors and a lot of people say that any majors can technically apply. You just have to take the LSAT and apply.

Not exactly.

To become a patent litigator you must have a BS in either the physical sciences (Chemistry or Physics), Natural Sciences (Biology, Biochemistry, etc) or knowledge in Engineering or Computer Science. Patent law requires a comprehensive knowledge of science and technology, since you will be dealing with people's inventions and as such you need the requisite background in order to practise. Majoring in philosophy gives you an edge in analysing arguments in Law school, but the practise of Patent law is very different from other fields of law.

If you don't have a degree in science, you DO have the option of taking the necessary classes to fulfill the coursework and sit for the patent bar, but fulfilling the coursework that way is essentially the same thing as taking all the courses for Physics, Biology and Chemistry majors anyway.

Most of the lawyers I know were either history or philosophy majors.There are some distinct advantages to majoring in the physical sciences when dealing with patents. Maybe you should consider Intellectual Property Law? If you like dealing in ideas (philosophy) more than hard science, why not check out that avenue?

-Good Luck

The answer is no. I note that a patent lawyer is a lawyer that is admitted to practice before the U.S. Patent and Trademark Office. Non-patent lawyers can litigate patent cases, but the competition for that work is pretty fierce. Here is the source that defines the educational requirements for patent lawyers:

Good Luck to you.

Maybe you can, but you still need to study the law first.
