Using the gerund (動名詞) "infringing" and the to-infinitive (不定詞) "to demand" together creates a parallelism problem in this sentence. Consider changing one of the verb forms to match the other one.

Gerunds and infinitive forms should not be mixed in a sentence. When the infinitive form (不定詞) is used, the marker "to" can be included or removed after the first use.
