Short answer. Not individually. Article 1631 makes a seller of a lump-sum bundle of rights, rents, or products answer for the legitimacy of the whole in general, but not for each separate part, unless you are evicted from the whole bundle or from the part that was worth the most.
What the law says
One who sells for a lump sum the whole of certain rights, rents, or products, shall comply by answering for the legitimacy of the whole in general; but he shall not be obliged to warrant each of the various parts of which it may be composed, except in the case of eviction from the whole or the part of greater value.

The seller answers for the bundle as a whole
Article 1631 addresses a sale where the price is not broken down by item but covers the entire bundle at once. It states that one who sells for a lump sum the whole of certain rights, rents, or products, shall comply by answering for the legitimacy of the whole in general. This means the seller is responsible for the overall package genuinely being what it was sold as, but the warranty is pitched at the level of the whole transaction, not itemized down to each individual right or component within it.
No separate warranty for each individual part
The same article limits how far that responsibility reaches: but he shall not be obliged to warrant each of the various parts of which it may be composed. If one small component of the bundle turns out to have a problem, that alone is not automatically a breach of warranty, because the seller never promised each individual piece separately. A lump-sum sale is treated as a sale of the package as a unit, and minor defects in individual parts do not, by themselves, trigger the seller's warranty.
The exception for losing the whole or the most valuable part
This limitation has a real boundary. The article carves out the case of eviction from the whole or the part of greater value, meaning that if you are dispossessed of the entire bundle, or specifically of the part that was worth the most within it, the seller's warranty is triggered after all. So while small, individual defects generally will not support a claim, losing the whole bundle, or its single most valuable component, is treated seriously enough to bring the warranty back into play.
What this means for a buyer of a rights bundle
If you bought a lump-sum bundle of rights, rents, or products and discover an issue with one minor part, Article 1631 generally will not give you a warranty claim on that basis alone. Your position is stronger if the problem affects the bundle as a whole or specifically the part that carried the most value, since that is the scenario the article treats as serious enough to hold the seller answerable despite the lump-sum structure of the sale.
