I am just a starter. the PLI study package is soo expensive. I am thinking of buying 2nd hand. but how can I know that I will not be cheated? is there any trick to follow?
or shall I just buy new study material?
thanks a lot!
Many people have sold their used PLI stuff on ebay including myself.
Let me warn you however. The latest version I think is from 2006 and does not have enough material on some of the main topics the PTO is currently emphasizing for the test. Namely, appeal, reexams and PCT. I got a ton of questions on these topics and had to supplement my PLI by reading the MPEP, etc. I am not sure if PLI has a newer version out to reflect the current trend. I would call PLI up and find out.
If you can afford it, I hear PRG (Prof. Kayton) is outstanding but it may bog you down with details. This may reflect more of what the PTO tests, but it is expensive.
