What college major is suggested for a student interested in becoming an intellectual property attorney?
The best major is science or engineering. There currently seems to be more demand for biology (biotech) and electrical engineering backgrounds for patent prosecution - but this might change in the future. If you know that you want to go to law school already, then it's also important to maximise your undergraduate GPA, which will be a factor in which law schools you can get into.
This answer is almost a given coming from an attorney, but "it depends." IP Law covers patents, trademarks, copyrights and trade secrets, as well as the licensing and litigation thereof. While I totally agree with the other answers regarding becoming a patent attorney, there are myriad opportunities in IP Law for the non-scientist/engineer. A strong economics background would be helpful when drafting complex licensing agreements. An arts or literature background could help when representing copyright or trademark clients. And skill as a litigator has far more to do with personality than college major. If patent law is your goal, try to look ahead to what technologies will be big when you graduate (water/agricultural tech? energy? robotics? tough call), and pick a major in one of those fields.
Whatever your interest, assess your strengths and work towards those. And if you still can't make up your mind in undergrad there's always grad school! Law firms love advanced degrees.
The first step in becoming an IP attorney is to become a scientist / engineer. Once you have your Bachelor's, you go to law school after which you take the Bar Exam (to become an attorney), and the Patent Bar exam (to specifically be an IP attorney). In order to qualify for the Patent Bar Exam, you must have a bachelor's degree in a technical field.
So — the college you should go to should be any school with a great science / engineering program. Hope that helps!
