IPC, in the sense filed here, is a name for a crime: copying someone else’s work — a book, a film, a song, a computer program — and selling those copies as if they were yours. Official English and some news reports use the three letters; everyday talk more often says piracy, or talks about fake copies.

IPCIPC（這裡收錄的意思） in the sense filed here在這裡收錄的意思裡 is a name for a crime是一種犯罪的名稱 copying someone else’s work也就是複製別人的作品 a book, a film, a song, a computer program像書、電影、歌曲、電腦程式 and selling those copies as if they were yours然後把那些複製品當成自己的來賣 Official English and some news reports正式英文和一些新聞報導 use the three letters會用這三個字母 everyday talk日常說法 more often says piracy比較常說piracy（盜版） or talks about fake copies或說是假貨、盜版品

The letters are probably a short form of intellectual property crime — crime against someone’s work or ideas — though people almost never expand them in a sentence. It is serious, legal-sounding language, not playground talk.

The letters這幾個字母 are probably a short form of intellectual property crime可能是intellectual property crime（侵害智慧財產權的犯罪）的縮寫 crime against someone’s work or ideas也就是侵害別人作品或點子的犯罪 though people almost never expand them in a sentence不過幾乎沒有人會在句子裡把它寫全 It is serious, legal-sounding language這是聽起來很正式、法律味很重的用語 not playground talk不是隨口聊天的用語

Though actually, the same three letters are reused in other rooms, so if the sentence is not about copying and selling someone’s work, you may be looking at a different IPC.

Though actually不過其實 the same three letters are reused in other rooms這三個字母在別的領域也被拿來用 so if the sentence is not about copying and selling someone’s work所以如果句子講的不是複製、販賣別人的作品 you may be looking at a different IPC你看到的可能是另一個IPC
