Preserve in example sentence
Any viable solution requires that the following conditions be satisfied:- drug companies – whether patent holders or generic drug producers – must provide drugs to poor countries at prices near to production costs;- drug prices in rich countries must remain higher through patent protection to preserve incentives for innovation;- rich and poor markets must be separated, so that cheap drugs from poor countries are not smuggled into rich countries (or are not allowed in legally through parallel-market imports);- governments in rich countries must provide substantial assistance to poor countries, so that the poor – who are too poor to afford these drugs even at reduced prices – can make use of them.
