So I agree; coding around patents is difficult given that they tend to be so hard to read and understand.
The claims in particular are indeed technical and difficult for a lay person to readily understand. But the background, the prior art and the description of the implementation are not. Background and prior art are a summary of the technical context and I have never had any difficulty reading or understanding this section. The description may be rather long winded as it has to detail how to implement the invention so that it may be implemented from the description by someone skilled in the art, but it isn't legalese and should certainly be understood by the inventor! The lawyer can't write this by him/herself.
I can certainly sympathize with those who can't follow the claims (although I have found it to be perfectly possible with determined effort), but I simply fail to understand how a lawyer turns it into something "I can't understand any more." Find alien and unfamiliar - yes. But incomprehensible?
As part of that arrangement, it seems like we ought to require that the disclosure be in English, not merely in a tongue that shares some English words and syntax.
Alternatively, you could say that the point of "legalese" is to define and convey ideas more explicitly than they can be defined and conveyed in English. Try writing a contract in "Plain English" - it will necessarily be full of ambiguity and uncertainty, which defeats the purpose of having a written contract.
Similarly, although programmers don't write code in "Plain English" I don't think we should begrudge them the right to keep using obfuscatory programming languages - even if it keeps the bastards employed.
I also believe that, by defining one's terms clearly, it should be possible to write unambiguous plain English contracts. Additionally, an English-parsable legalese needn't necessarily lead to an unambiguous interpretation when parsed as English, so long as it is unambiguous when parsed as legalese, and most of the meaning is retained when parsed as English.
